Overview

The GS868 flow meter from Panametrics is specifically designed for mass flow measurement of steam. It is suitable for use on most types of steam application including saturated or superheated steam, pneumatic power stations, heating, ventilating and air conditioning (HVAC), water purification and distillation, chemical and petrochemical industries and more.

The GS868 steam flow meter is a complete package which offers wide rangeability, no pressure drop, easy installation, high accuracy and requires low maintenance.

The GS868 flowmeter has no parts which collect debris so therefore requires no cleaning. There are no moving parts to wear out so no lubrication is needed. As the transducers do not obstruct the flow, they will generally not cause any pressure drop.

Sending data to where it needs to go is easy with the standard or optional range of additional analog outputs and alarms. Outputs can be set up and calibrated by using the built in keypad or from a computer using the PanaView software.

Maximum accuracy can be achieved by using the two channel steam flow meter to measure two different paths at the same location. The two channel version can also be used to measure the flow in two different pipes.
