Food Industry Batch Level Control

Food Industry Batch Level Control

Many food processing facilities employ batch processes in their production facilities where the operator starts with an empty vessel and create the final product by adding multiple ingredients.

The batch process requires the operator to know the amount of each ingredient added to the blending vessel. Point-level controls speed the process by establishing setpoints at each ingredient fill point,  often accomplished with several level sensors, each detecting one ingredient.

Batch food processing applications are challenging. The sensor must include sanitary fittings and CIP (Cleaned In Place) design. In many cases, the ingredients and final products are dense and sticky, wreaking havoc on some technologies such as mechanical switches and tuning forks. Products in the blending vessel may be thick and could cause damage to fragile sensors. Finally, many batch processes are agitated, causing false tripping due to splashing material. 

As you can tell, proper level sensing technology is critical. Choosing the wrong technology will cause ruined batches, costly downtime, and the possibility of overfilling.

The Drexelbrook Multipoint II offers the best solution for batch process control applications in the food industry.

Drexelbrook, a leading manufacturer of level controls, recommends its RF Admittance Multipoint II. It provides a total solution for the batch processing of food. The RF Admittance Multipoint II is a single sensing element and a single mounting point from the top of the vessel using a sanitary Tri-Clamp fitting and has no moving parts to wear out or get hung up. The Multipoint II sensor is a 3A sanitary designed steel rod with Kynar or TFE insulation developed for CIP procedures. RF Admittance Cote-Shield driven shield circuitry ignores heavy coatings on the sensing element, preventing false alarms. The Multipoint II consists of three independent DPDT relays, and control points are set anywhere along the vertical sensing element.

  • 3A designed sanitary sensing elements
  • No moving parts
  • 3 control points on one vertical sensing element
  • Cote-Shield circuitry eliminates false alarms due to coatings
  • Designed to endure Clean In Place (CIP) demands

Setting Up and Calibrating the Drexelbrook MultiPoint II Level Switch


This video demonstrates how to calibrate and set the Drexelbrook MultiPoint II level switch.

The Drexelbrook Multipoint II level switch product offers three control points located anywhere along a single vertically inserted level sensing element. This level switch can be used to provide high level, high-high level, and low level control points. It also provides an adjustable differential feature for one of the control points for pump on/pump off control making it ideal for sump level control. It is designed to be intrinsically safe for Class I Groups A,B,C,D and Class II Groups E,F,G (Div. 1 and 2). The unit is mounted in FM approved explosion proof housing. The MultiPoint II has no moving parts and the need for maintenance is therefore eliminated. The Drexelbrook MultiPoint II is an economical solution for processes requiring multiple operating points.
