Why is there only 24V for vortex power supply? Vortex flowmeter is a type of transmitter, which mainly includes temperature, pressure, flow rate, liquid level and other categories; In addition to the interference reasons mentioned by Lead Xian upstairs, there are several other reasons:
1. Transmitter instruments need to enter the DCS or PLC system to obtain information. The most convenient connection method for these systems is a two-wire instrument (24V without power supply, the circuit is directly connected in series with a 250 ohm high excitation impedance to measure the signal).
2. The vortex flowmeter itself does not require too high power, a two-wire system is sufficient, and it can also be equipped with HART protocol, which means that two wires can have 24V+4~20mA+HART.

4、 The transmitter is powered by 220V, and there are two main possibilities:
1. Special on-site requirements or user customization;
2、 For instruments with high power consumption such as electromagnetic flowmeters, it is not meaningful to use 24V (a 24V power supply can only carry a few instruments and the circuit pressure drop is too large). 5. For two-wire vortex street flowmeters, 24V power supply actually refers to 10V~30V or 12~32V, depending on the manufacturer. 2.7F2C80-WM19/0 flowmeter 7F2C80-ABCCAACAAAD2SKA1+Z1 Endress
