Flow transmitters and totalizers
Flow transmitters convert the signal from a flow sensor into a standard output for control systems, while totalisers accumulate flow over time to give a running volume or mass. Together they turn a raw measurement into usable process data.
Overview
Most flow sensors produce a raw signal such as pulses, a small voltage or a frequency. A flow transmitter conditions this signal, applies scaling and, where needed, linearisation or square-root extraction, and provides a standard analogue current signal, pulse output or digital communication. A totaliser integrates the flow rate over time and displays or transmits the cumulative quantity, often with resettable and non-resettable totals, batch counters and relay outputs for alarms or batch end. These functions may be built into the meter or supplied as separate panel or field-mounted units.
Selecting the right transmitter or totaliser
Start from the sensor you have or plan to use and the signal it produces. Then decide where the unit will be mounted (field or panel), what it must send to the control system, whether local display and totalising are needed, how many alarm or batch relays are required, and the available power supply. Enclosure and hazardous-area needs also apply.

Frequently asked questions
What information do you need to quote a flow transmitter or totaliser?
Tell us the flow sensor type and the signal it produces (pulse, frequency, analogue or millivolt), its scaling or pulse value, the units to display, the outputs and relays needed, panel or field mounting, the power supply and any enclosure or hazardous-area requirement. If the unit is for an existing meter, include its model and wiring details.
Can a totaliser be added to an existing flow meter?
Often it can. If the existing meter provides a pulse, frequency or analogue output, a separate totaliser can usually read it, scale it and show both rate and total. The meter's output type, pulse value or range, and the supply voltage need to be known to confirm compatibility. Send the meter details and the functions you need.
