If the guaranteed current is greater than the start-up current of the mass flow meter
Thread Content
Mass flow meter, starting current is 1A； The transmitter receives 24V power and a 24mA signal in the transmitter room; it is also connected to the mass flow meter sensor. The distance between the cabinet room and the transmitter is 50m, and we would like to use the ZA-DJYVRP1*2*1.5 computer cable. How do I calculate the voltage drop, or current, etc.? Can I be sure that the mass flow meter will start up successfully? My calculation is: current = voltage/resistance. Voltage: 24V ； Resistance: 1.2 ohms (cable resistance) + 600 ohms (transmitter resistance) = 601.2 ohms ； The current calculated is 0.04A, which is less than the starting current. I don’t know how to calculate it. Help! ! !
Consult the manufacturer; it mainly relates to the power supply and wire gauge: 1. When the diameter is larger, 220VAC power is used
Consult the manufacturer; it mainly relates to the power supply and wire gauge: 1. For larger diameters, 220VAC power is used, for diameters of 4” and above. Powered by 2.24VDC; the wire gauge should not be too thin.
