Frequently Asked Questions

What is a wet gas flow meter?

A wet gas flow meter measures gas flow in environments where moisture or liquid is present. It uses a sealed chamber with liquid displacement to ensure accurate readings even in humid conditions.

Can your test benches handle smart gas meters?

Yes, our MDRK series test benches provide 4 types of adjustable power supplies and support communication protocols for calibrating smart gas meters with pulse or digital outputs.

Are your calibration systems traceable to national standards?

Yes, our active piston provers and sonic nozzle facilities are calibrated against primary standards and provide full documentation for metrological traceability.

Do you offer international support?

Yes, we serve clients globally with technical support, installation guidance, and remote diagnostics available in multiple languages.
