Batch Controllers

Contrec Batch Controllers provide the ideal solutions for the accurate dispensing and measurement of fluids for a variety of industries from food and beverage to truck loading. 

With over 50,000 instruments installed worldwide Contrec Batch Controllers continue to provide the standard by which our competitors follow.  Contrec’s accurate and reliable batch controllers range from the 400 series ideal for Intermediate Bulk Containers (IBC), drum filling and food processing to the 515 series instruments, suitable for more complex batching applications.

The 515 Series delivers highly accurate field controllers for the process and petroleum industries. It utilises a common, advanced hardware and the functionality is determined by software which is tailored to individual applications. This allows multiple channels and outputs to be configured; allowing applications such as additive injection, ratio blending, temperature and density corrected batching to be easily configured.


For example, our Batch/Ratio Process Controller (BR01) application is a batch ratio controller for the delivery of two products into a vessel at specific preset (but adjustable) ratios using volumetric frequency inputs.

Batch control can operate in preset or on-off modes, while flow control can be set to various loop control modes. It offers single or dual stage control as well as no flow, leakage and overflow error detection. Additionally it has a remote run/stop/reset function.

As with all the 515 Series batch controllers the BR01 is suitable for use in control room, field mounting or hazardous areas.
Introduced in 1992, our 400 Series quickly became the industry standard for accurate and reliable flow monitoring and control. In fact, many of those early instruments are still in service today. However, we continue to look at innovative ways to make good flowmeters even better and so our field proven 400 Series has recently received an upgrade. Taking many of the best features of the 400 Series, such as the large LCD displays, rugged reliability and auto run and flow alarm features, we’ve added many more features to the 424 Batch Controller model as standard.


The new 424 Batch Controller will interface to most flowmeters with pulse or frequency outputs. Batch total, flow rate, accumulated total and preset value can all be displayed in engineering units on the large LCD display. The instrument comes fitted with both RS232 and RS485 communication outputs which to allow it to print delivery tickets and also be monitored and/or controlled remotely from the control room.


The 430D Batch Controller, for example, is suited to applications where precise measurement and control of variable batch quantities are required. Batch quantities and calibration parameters are entered via a full 12-key numeric keypad. A bright LED display provides an excellent operator interface even in dimly lit environments.
Contrec has an international reputation for delivering accurate and reliable field controllers. Our instruments continue to prove themselves in the field; years after their installation.
