Centralising third‑party remote access is a practical way to cut attack surface and improve repair governance; treat tool access as a contract requirement tied to SLAs and approved tooling

Key takeaways

  • Centralising third‑party remote access is a practical way to cut attack surface and improve repair governance; treat tool access as a contract requirement tied to SLAs and approved tooling.[2]
  • Make calibration scheduling a planned procurement item with qualified service blocks to avoid premium emergency calibrations and preserve measurement traceability.[3]
  • Obstructed-tank level measurement is an operational problem, not just a specs debate — false echoes can cause overfills, spills and downtime; procurement should price installation, positioning and validation into purchase decisions.[1]
  • Non-contact FMCW radars lower routine maintenance needs but sometimes need positioning, software setup or alternative tech; these interventions can be disruptive and costly if they become recurring.[1]
  • Remote access maturity is a staged program (move vendors onto a single approved tool then broaden vendor groups); this is an achievable commercial lever but needs contract scope and acceptance testing.[2]

What changed since last run

  • Shifted procurement focus from automation/HMI spare provisioning and NSW project readiness to measurement accuracy, calibration scheduling and OT remote‑access governance.
  • Added remote‑access centralisation as a supplier leverage and security control item not emphasised in the previous brief.

Key facts

  • Non‑contact FMCW radar favoured for many applications
  • Obstructions create false echoes that can produce overfill or underfill
  • Some mitigation measures involve disruptive installation work
  • Tool sprawl common — multiple remote‑access tools in many OT environments
  • High incidence of third‑party related cyber attacks reported in the sector
  • A staged maturity model (levels 0–4) guides adoption

Why it matters

Centralising third‑party remote access is a practical way to cut attack surface and improve repair governance; treat tool access as a contract requirement tied to SLAs and approved tooling. Make calibration scheduling a planned procurement item with qualified service blocks to avoid premium emergency calibrations and preserve measurement traceability. Obstructed-tank level measurement is an operational problem, not just a specs debate — false echoes can cause overfills, spills and downtime; procurement should price installation, positioning and validation into purchase decisions. Non-contact FMCW radars lower routine maintenance needs but sometimes need positioning, software setup or alternative tech; these interventions can be disruptive and costly if they become recurring

Cost / money

  • Centralised remote access reduces hidden recovery and incident costs but requires upfront tool licensing and change management spend; budget as a line item in IT/OT procurements.[2]
  • Outsourced calibration performed during planned shutdowns creates predictable service spend; failing to plan pushes work into premium emergency windows.[3]
  • Upgrading level measurement (narrow‑beam or guided wave options) increases upfront procurement and installation costs but can lower recurring maintenance and spare part usage over time.[1]

Supplier / commercial

  • Require OEMs and integrators to adopt the approved remote‑access tool or accept limited access windows; this creates a commercial requirement you can use in award negotiations.[2]
  • Calibrations are a buyable service block — use retainer or scheduled‑visit pricing to shift risk and avoid ad‑hoc emergency rates from third‑party providers.[3]
  • Specify antenna type, beam angle and installation positioning in purchase orders for level sensors to avoid short validity quotes and post‑delivery change orders from suppliers.[1]

Safety / operations

  • False echoes in obstructed tanks can produce overfill or dry‑run events; validated sensor selection and installation checks are a safety control, not optional testing.[1][3]
  • Tool sprawl for third‑party remote access materially increases cyber‑physical risk and time to recover; centralisation improves governance and mean‑time‑to‑repair.[2]
  • Poor calibration undermines preventive maintenance and traceability, increasing operational failure and compliance risk unless certificates and uncertainty are enforced.[3]

What to watch

  • Early‑signal: vendors marketing non‑contact radar as plug‑and‑play may understate installation positioning needs and false‑echo workarounds; validate with site pilots.[1]
  • Vendors and integrators may resist moving to a single remote‑access tool for contractual or tooling‑preference reasons; expect negotiation and staged adoption.[2]

Top stories

Story 1Processonline

Ensuring reliable level measurement in tanks with internal obstructions

Signal moderateSource-grounded
Source notes [1]Read source

What happened

Process Online explains that tanks with internal structures produce false echoes that make top‑down radar level measurement hard to trust. The most operationally relevant detail is that narrow‑beam FMCW radars reduce some interference but positioning and additional measures are often required, which can be disruptive and costly. Watch whether suppliers offer validated installation services or insist on pilots before wider procurement

Buyer takeaway

Treat level‑measurement purchases as system buys (sensor + installation + acceptance) rather than standalone SKU buys

Cost / money

Shifts spend from recurring maintenance to upfront installation and validation costs if obstructions require repositioning or alternate tech

Supplier / commercial

Use PO terms to require supplier‑backed acceptance tests and spare provisioning to reduce change‑orders

Safety / operations

Incorrect level reads can cause overfills, spills and downstream equipment damage; validation is a safety control

What to watch

Vendors may present non‑contact radars as plug‑and‑play; validate on‑site before scaling

Key facts

  • Non‑contact FMCW radar favoured for many applications
  • Obstructions create false echoes that can produce overfill or underfill
  • Some mitigation measures involve disruptive installation work

Source excerpts

However, while deflector plates can improve measurement reliability in some applications, their installation presents several practical challenges. In tanks with limited access or complex internal structures, positioning the plates correctly can be difficult
High-frequency radar level transmitters with narrow beam angles can reduce the risk of interference in obstructed tanks, but they can’t always avoid it. Accurate and reliable level measurement is fundamental to the safe and efficient operation of process plants
Ultimately, the misinterpretation of a false echo compromises not only safety, but also operational efficiency, product quality and profitability. This makes effective discrimination between true and false echoes a critical requirement for reliable non-contacting radar level measurement

How to centralise remote access: securing all access to your OT systems

Signal strongSource-grounded
Source notes [2]Read source

What happened

Process Online outlines a maturity model for centralising remote access to OT systems to reduce tool sprawl and cyber risk. The operational detail: many organisations use multiple remote tools today, expanding attack surface and causing governance issues, so moving vendors onto an approved tool plus staged onboarding materially reduces third‑party risk. Watch vendor pushback and plan staged vendor groups rather than one‑step migration

Buyer takeaway

Centralise access to reduce cyber risk and create a negotiable procurement requirement (tool + SLAs)

Cost / money

Requires investment in tooling and onboarding but lowers incident response and recovery costs over time

Supplier / commercial

Use access requirements in contracts to shift compliance and tooling costs onto vendors or to set acceptance criteria

Safety / operations

Reducing remote‑access sprawl lowers the chance of unauthorized changes that could affect plant safety or uptime

What to watch

Expect staged adoption; some vendors will prefer their native tools and require negotiation or compatibility work

Key facts

  • Tool sprawl common — multiple remote‑access tools in many OT environments
  • High incidence of third‑party related cyber attacks reported in the sector
  • A staged maturity model (levels 0–4) guides adoption

Source excerpts

Level 4: Cost optimisation — The final stage brings all remote access through your centralised tool
Level 1: First-party access — Internal engineers use a centralised remote access tool
Centralising remote access and reducing tool sprawl creates benefits for engineer and system productivity, reduces risk, and adds control and governance. Remote access is critical for cyber-physical systems (CPS) in industrial environments
Story 3Processonline

Calibration explained: principles, processes and modern reporting

Signal moderateSource-grounded
Source notes [3]Read source

What happened

The calibration article summarises principles and shows calibration is central to traceability, preventive maintenance and accurate measurements. Operationally important: calibration is often carried out on site during planned shutdowns and external providers are commonly used, so planning and documented certificates matter for compliance. Watch calibration uncertainty and certificate completeness when awarding service contracts

Buyer takeaway

Buy calibration as a scheduled service with clear deliverables (certificates, uncertainty, traceability) rather than ad‑hoc labour

Cost / money

Consolidating calibration with scheduled blocks reduces emergency premium spend from unscheduled calls

Supplier / commercial

Negotiate block bookings or retainer models to secure availability and predictable pricing

Safety / operations

Accurate calibration underpins preventive maintenance and regulatory compliance; lapses increase failure risk

What to watch

Ensure certificates include traceability and uncertainty data; incomplete certificates increase rework risk

Key facts

  • Calibration compares instrument outputs to traceable reference standards
  • Onsite calibration common during planned shutdowns using external providers
  • Calibration certificates document traceability and measurement uncertainty

Source excerpts

Onsite calibration is a common practice in industrial environments, particularly during planned production shutdowns when multiple instruments require calibration
