Instrumentation and measurement
Instrumentation & Process Measurement
Flow, pressure, level and temperature instruments, together with control valves, pneumatic components and accessories, specified around the measured variable, process fluid, range, accuracy and the signal your control system expects.
Typical challenges
Where customers usually start
- Readings that drift or do not match plant balance calculations
- Selecting a flow measuring principle for difficult or changing fluids
- Matching output signals and protocols to an existing control system
- Instruments needed for hazardous or harsh environments
- Calibration and traceability records required for audits
- Replacing obsolete instruments without re-engineering the installation
Measurement that fits the process
Most measurement problems start at specification. A flow meter that suits clean water may not work on a slurry, a non-conductive fluid or a gas; a pressure transmitter ranged far above normal operating pressure loses useful resolution; a level sensor that ignores foam, density changes or tank geometry will drift from reality. This capability covers flow meters across several measuring principles, pressure transmitters, transducers and gauges, calibrators, level and temperature instruments, flow switches and controllers, along with the solenoid valves, cylinders, air preparation and accessories that sit around them.
Instrument choice is driven by the fluid and the installation as much as by the instrument itself. Straight-run requirements, mounting orientation, process connection, ambient conditions and the need for hazardous-area protection all influence which principle and which model are appropriate. The supporting items matter too: isolation valves, manifolds, impulse lines and cable entries determine whether an instrument can be maintained and calibrated without disturbing the process.
Information that decides the specification
Before recommending an instrument we need the measured variable, the process fluid and its condition, the normal and maximum range, the required accuracy, the process connection, the output signal and communication protocol, the available power supply, any hazardous-area classification and whether calibration evidence is needed. Ambient temperature, line size and installation constraints also matter. Unknown values are listed openly so that they can be confirmed with your process or maintenance team before a final selection is made.

Frequently asked questions
How do I choose between flow meter types?
Start with the fluid: whether it is liquid, gas or steam, whether it conducts electricity, and whether it carries solids or bubbles. Then consider line size, flow range, required accuracy, available straight pipe, pressure loss and budget. Each measuring principle has fluids and installations it suits well and others it does not, so the process data usually narrows the choice quickly.
What output signals can instruments provide?
Common options include analogue current signals, pulse or frequency outputs, relay contacts and digital fieldbus or serial communication. The right choice depends on what your PLC, DCS or recorder can accept. Please state the required signal and protocol in your enquiry so that compatible models are proposed.
Can calibration certificates be supplied with instruments?
You can request calibration documentation when you enquire. State the range and calibration points you need and any traceability requirement, so that the available documentation can be confirmed for the specific instrument in the proposal.
