The N1500 series of Universal Process Indicators are high performance instruments used for monitoring analogue signals found in the majority of industrial and laboratory processes.

Designed specifically for flow applications, this dual display instrument shows both the instantaneous flow rate and the totalised value. It can accept a range of standard inputs which are easily selected by the user. Unusually both Analogue and Pulse inputs are available in the same unit as standard, so it can integrate an analogue (instantaneous flow rate) signal to give totalised flow and differentiate a pulsed signal (volume flow) to give instantaneous flow rate, which can then be transmitted on the 4-20mA output. It can also act as a pulse divider, retransmitting a input pulse as a slower (or faster) output pulse.
