    – Improve product quality
    – One or two stage valve control
  • Versatile 
    – Works with most flowmeters
    – Watertight front


This instrument is used in hazardous areas to automatically batch a precise quantity of liquid. It accepts pulsed frequency signals such as those generated by turbine, positive displacement or pelton wheel flowmeters.


To start a batch you simply press the run button. It will control pumps and valves to deliver your required volume of liquid. One display will show you the batch count whilst the other will show the preset quantity.


The setup is easy using the keypad and it can be supplied preset for your application. The displays can be set for any units e.g. litres or gallons. During setup the pulses per litre, decimal point positions and valve delays are entered.


The 214Di requires a DC power supply and batteries provide back up so that totals are not lost if power is interrupted. It is mounted directly on to your flowmeter, wall or pipe.
The two transistor outputs can be used to control valves and pumps. This allows for one or two stage batching with slow start up and/or slow shutdown of the batching process. The first output will energise at the start of the batch and de-energise when the batch is complete. The second output can be set to energise at a fixed time after the start, and to de-energise at a fixed quantity before the end of the batch.

Intrinsically Safe Installation

The 214Di is certified for use in Class 1 Zone 1 hazardous areas with approved sensors and solenoids such as the Apollo IS coil and Namur sensor.


The instrument is housed in a polycarbonate enclosure that is weatherproof. Cables are inserted through waterproof cable glands.
