Description

Custom designed for flow applications, the Flow Rate & Totalisation Panel Meter N1500-FT measures and displays both the instant measured value and the totalised value. One model is capable of reading a 4-20 mA signal or a pulsed signal. Input type is fully software selected. Several display modes are available and instrument can be ordered with up to 4 relays plus digital communication. It boasts dual retransmission outputs: one 4-20 output, typically for instant flow, and the other is a pulse (NPN) output, typically for totalised flow. Both outputs are isolated.

Ideal for water and other liquid distribution systems, the N1500-FT is a flow indicator specifically designed for control and precision. It provides flexibility in measuring and displaying both instantaneous and totalised flow rate, and also offers up to four outputs that accept custom configurations such as alarm and dosage control.

A flow indicator output can be used to switch on the start of dosing and off when the desired volume is reached. It is compatible with flow sensors with pulse, dry contact, magnetic pick-up, or 4-20mA outputs. As a differential, the 4-20mA input can also be used to indicate a second variable of choice, allowing, for example, the simultaneous indication of flow rate and pressure.

Features
