NUFLO TMP-100 Pulse Divider Circuit

Overview

The NUFLO TMP-100 turbine meter pulse divider circuit is designed to provide a pulse output representing a user-defined unit volume from a remote mounted turbine meter. This output may be interfaced to RTUs, totalizers, or field computers. 

The NUFLO TMP-100 turbine meter pulse divider circuit is specifically designed for turbine flow meters and is to be mounted in a user supplied weather-resistant enclosure or control room environment. The NUFLO TMP-100 turbine meter pulse divider circuit receives its signal from the magnetic pickup and with a divisor range 1 to 524,287, provides a pulse output representing a unit volume over a wide range of applications. An adjustable potentiometer is provided for the input signal sensitivity. Nineteen-position divisor dip switches make calibration extremely simple. 

The pulse out duration on the NUFLO TMP-100 turbine meter pulse divider circuit is adjustable by potentiometer from 60 ms to 800 ms with three different pulse outputs available, dry contact relay, opto-isolated emitter collector output and non-isolated electronic pulse out. The electronic pulse out is dip switch selectable for a negative or positive pulse. The NUFLO TMP-100 turbine meter pulse divider circuit may be powered by a 10 to 28 VDC power source. A header has been provided to allow for connection of optional circuit assemblies such as the 4 to 20mA output rate option circuit.
