Gilflo Flowmeters System Overview
Description The Spirax Sarco Gilflo flowmetering system consists of 3 major parts:
1. The Gilflo 'B' pipeline unit. This is installed in the line where the flow is to be measured. Using impulse pipework, this is connected to: 2. A differential pressure transmitter which measures the differential pressure across the Gilflo and converts it into a 4 - 20 mA signal. This signal can then be transmitted to: 3. a - A Chart recorder, EMS / BMS or M750 display unit. b - An M850 flow computer.

Note : The Gilflo pipeline unit can be used to measure the flow of most industrial liquids, gases and vapours within the pressure and temperature limits detailed in the appropriate TI document(s). M850 - Pressure and / or temperature compensated saturated or superheated steam. In addition heat metering is possible by replacing the EL2600 pressure transmitter with an EL2271 temperature transmitter in the condensate return line. Caution: Steam mass flow transmitters are uniquely configured at the factory to work with a single, specific Gilflo, ILVA or M410 orifice plate flowmeter. For correct operation the configured transmitter must always be installed with its allocated flowmeter. Labels on the packaging give the serial numbers of the matched products.
