Frequency output: Frequency 2KHz (configurable 0-5 kHz), corresponding to the
upper limit of the flow range
Pulse output: corresponding flow rate volume of each pulse (configurable) ; output
pulse width: 0.1ms ~100ms , space ratio:1:1; Fmax <= 5000 cp/s
Electric wiring diagram 750Ω under load; Imax ≤ 22mA Current flow percent

Additional remarks: pulse output is OC gate output, it needs external power supply.
The general counters are equipped with pull-up resistors, and the signal can be
directly connected therein.
Manufacturer's suggestion: use a pull-up resistor R of 2K, 0.5W, and 24V DC
power supply for power supply
