Schlumberger Mass Flowmeter

What pressure, flow and temperature is it rated for?

Maximum rated pressure is 1200 PSI at 100°F, with maximum temperature rating of 400°F at 815 PSIG. The listing includes a frequency specification of 100.69 H2 @ 60.7, but does not provide flow range or capacity data—request calibration sheets or specification documentation from the seller to determine flow capabilities for your application.

What gases is it compatible with, and has it been oxygen cleaned?

The frequency specification references H2 (hydrogen), indicating this unit was likely calibrated or used for hydrogen service. The listing does not indicate whether it has been oxygen cleaned or specify which gases it is compatible with—contact the seller to confirm previous service history and cleaning status if you require oxygen or reactive gas compatibility.

What materials are the wetted parts?

Wetted parts are constructed from 316L stainless steel. Coriolis mass flowmeters typically have wetted components including the flow tube, process connections, and internal sensor housings, all of which should be 316L SST in this unit based on the material specification provided.

What should I inspect before putting it into service?

Inspect the flow tubes for corrosion, erosion, or deposits that could affect measurement accuracy, and verify process connections and seals for damage. Request recent calibration data if available, as mass flowmeters typically require recalibration after extended storage or when moved between applications. Check the transmitter electronics for physical damage and verify that sensor cable connections are intact, as Coriolis meters rely on precise vibration measurement that can be affected by mechanical damage to tubes or sensors.
