Can the flow meter be measured in two directions?
Only suitable for measuring conductive liquids;
1, if you just look at the flow rate, you can, for example, electromagnetic flowmeter, whether you take the whole measurement or reverse measurements can be, in the premise of the electromagnetic flow meter settings, reverse measurements allowed.2, if you need to increase the amount of it, it is not easy to say, you are measuring the cumulative amount and you reverse the cumulative amount of measurement, how to convert? Whether you want to subtract or add, it depends on your situation.
Output only in one direction. The best use of mass flowmeter communication, density, temperature, pressure, instantaneous flow, total flow of all data can be displayed on the DCS screen; if the 4-20mA current input, can do the program in DCS to give time to manually switch separate cumulative metering.
