The F127 is a differential flow computer that calculates the corrected flow given a gas or liquid volume of a certain temperature. This powerful unit allows you to connect the unit displays the compensated flow rate, total, line temperature and pressure. The 4-20mA output mirrors the calculated differential flow rate. When ordering you must choose if you want to order the unit with the gas, or with the liquid equation for correct compensation. You can then connect two temperature inputs and two flow meter inputs and it will do the differential of the two adjusted flows. The F127 has optional inputs including Pulse, Coil, NAMUR, 4-20 mA or 0-10 V. The F127 is offered with a plastic, aluminum, or explosion proof enclosure, or it can be ordered to simply panel mount. The options for powering the unit are battery, IS battery, loop power, 80-240 VAC with sensor supply, IS 16-30 VDC, and 8-24 VAC/VDC. The F127-XI can be used in hazardous areas too, classification EEx ia IIB T4.
