Gilflo ILVA Flowmeters System Overview
Description The Spirax Sarco Gilflo ILVA flowmetering system consists of two major parts: 1. The Gilflo ILVA pipeline unit. This is installed in the line where the flow is to be measured. Using impulse pipework, this is connected to: 2. The M610 DP transmitter assembly. This measures the differential pressure across the Gilflo ILVA pipeline unit and converts it to a 4 -20 mA output signal. This output signal can be used in a number of ways: i- To act as a suitable input to an EMS / BEMS which can be programmed by the user to carry out the linearising of the output signal based on the calibration data that is supplied with each Gilflo ILVA flowmeter. Additional inputs from the EL2600 pressure transmitter and EL2271 temperature transmitter can be used to carry out density compensation for compressible flow applications ii- To supply an M750 display unit. This gives a non-compensated display of rate of flow and totalised flow. It is suitable for liquid, gas and steam applications where density compensation is not required. iii- To supply a Spirax Sarco M850 flow computer. Use of the pressure and temperature transmitters enables automatic density compensation to be carried out for compressible flow applications. See the relevant TI for details of pressure / temperature limits for flow computers. The Gilflo ILVA 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 TI's.

Installation Care must be taken to meet all the requirements of the Installation and Maintenance Instructions that are included with the equipment. Some installation points to watch are noted overleaf. In addition, heat metering is possible on saturated steam systems by replacing the EL2600 pressure transmitter with an EL2271 temperature transmitter in the condensate return line (M850 system only).
