PROJECTEnquire ↗Process instrumentation
From water balances to batching and process flow: the measurement point must suit the medium, operating range and intended use of the result.
Operating context
Selection starts with actual minimum, normal and maximum flow rates. A complete solution includes the sensor, process connection, necessary compensation, electrical interface and signal verification. The distinction between operational monitoring and measurement for commercial transactions belongs in the initial specification.
Engineering priorities
Electromagnetic measurement is an option for conductive liquids. Lining and electrodes depend on the medium. Pipe filling, potential equalisation and the selected instrument’s installation requirements are part of the engineering.
Coriolis technology can measure mass flow directly. Selection considers pressure loss, operating range and entrained gas. Measurement stability must be assessed against the actual production cycle, including starts and short batches.
Vortex or differential-pressure measurement requires consideration of operating conditions, density and compensation. A primary restriction element also needs suitable geometry, pressure taps and impulse piping; an orifice plate alone is not a complete measurement chain.
We inspect and calibrate flowmeters on our own calibration line. The working range, medium, process connections, output signal and required measurement points are established for the instrument. Comparison results are tied to the identified meter and recorded conditions; checks of settings and measured-value transmission follow where specified.

Agreed with the proposal
The actual scope and acceptance criteria depend on the application and contract.
Selection in context
Select the principle against the fluid, actual flow range and installation conditions; the complete measurement point determines the resulting uncertainty.
On a small screen, scroll the table sideways to compare the selection criteria.
| Principle or option | Typical application | What to verify when selecting |
|---|---|---|
| Electromagnetic flowmeter | Volumetric flow of conductive liquids, such as utility water or conductive process solutions. | Conductivity, a full measuring tube, electrodes and liner, grounding, and manufacturer installation requirements.[1] |
| Coriolis flowmeter | Mass flow for liquid batching and material balances; gases where supported by the selected design. | Minimum and maximum flow, pressure loss, gas entrainment in liquids, vibration and required measurement response.[2] |
| Clamp-on ultrasonic | Retrofit or temporary measurement from the outside of existing pipework. | Pipe material, dimensions and lining, acoustic transmission into the fluid, bubbles or particles, and available straight length.[3] |
| Vortex flowmeter | Steam, gas and liquid flow within an appropriate operating range. | Sufficient flow for vortex shedding, flow profile, vibration and steam condition; density compensation for the required output quantity.[1] |
| Differential pressure across a primary element | Liquid, gas or steam flow derived from pressure difference across an orifice or another sized primary element. | Element and pipe geometry, density, measuring range, pressure loss, pressure taps and impulse-line arrangement.[4] |

Before we start
Clamp-on ultrasonics can be evaluated for suitable applications. Pipe material, condition, lining and the acoustic properties of the medium determine suitability.
It records calibration under stated conditions. Handover should also verify installation, units, scaling and the transmission of values into the control system.
