Dwyer Instruments PPM-220 | Pulse panel meter | 12-24 VDC | 2 relays | No transmitter
The Model PPM-220 powers the flowmeter with 5, 10, or 24 VDC after receiving a pulse input signal. The pulse can be transformed into a signal that can be sent over great distances to a PLC or other device by adding the 4–20 mA output option.
