The Welkin target flow meter measures the flow of liquids, gases and steam in process pipelines. It is used at oil and gas companies to monitor process parameters and track flows of the working medium.
The meter works by measuring the force the flowing medium exerts on a target mounted inside the pipeline. Flow pressure is transferred to the sensing element, allowing the flow of liquid, gas or steam to be determined precisely.
Meters of this type are used where the working medium carries enough momentum to act on the measuring element. That makes them an effective way to monitor flows in industrial pipeline systems.
What the flow meter is for
The Welkin meter measures the flow of liquid, gaseous and steam media in process pipelines. It is used to monitor production processes and to meter consumption of the working medium.
Its main field of use is oil and gas companies that need reliable monitoring of flow parameters in pipeline systems.
Advantages of the Welkin flow meter
Fast response
The meter displays a flow reading from zero to full scale in under one second. Where required, a damping function lets the response speed of the system be adjusted.

Frequently asked questions
What temperature range does the Welkin meter work in?
The standard version is rated for media from −40 to +250 °C. For higher temperatures a special target and body version is selected; parameters are confirmed at the ordering stage for the specific process.
Which media can the instrument handle?
The target flow meter works with liquids, gases and steam, including contaminated and viscous media. Unlike instruments with rotating elements, it has no moving parts in the flow, so solids carried by the medium do not cause failure.
Does the meter require verification?
Yes, the instrument is subject to periodic verification in line with the verification procedure and metrological requirements. The verification interval is set in the equipment passport.
How is the meter serviced?
Servicing amounts to periodic inspection of the target and a check of the measuring path. With no moving parts, the scheduled workload is lower than for turbine and impeller meters.
