Metal detection for liquids and pastes


  • Reliably detects metal contaminants in liquid and paste products
  • Easy to integrate into common pipeline systems, diameter from 1“–6“ / 25-150 mm
  • Stainless steel housing and frame are easy to clean, supplied tube is CIP-capable (Cleaning In Place)
  • Highest sensitivity with 4-quadrant technology
  • Intuitive control and easy installation through autocalibration and TeachAsssistant


Metalldetektor METAL SHARK IN Liquid, besonders stabile Verschraubung der Rohrleitung


The METAL SHARK® IN Liquid is developed for liquid and paste products. With its maintenance-free design and high-quality, hygienic construction, the metal detector is ideal for reliable use in the food industry.

METAL SHARK® IN Liquid can be easily integrated into all common piping systems for pumps, vacuum fillers or even sausage meat filling plants.

Three different valve models, optimally adapted to the respective product, guarantee a safe discharge of metallic contaminants.

Accessories & Extras

The CASSEL In Liquid can be supplied with three different reject valves for different product requirements. The pressure hose or product tube are also individually adapted to the requirements of your production. Signalling devices are available as well as adapted frame constructions.

In many cases, the CASSEL metal detector is also a critical control point. It is therefore important to check that the detector is working properly at regular intervals. For this purpose we offer the appropriate testing accessories or extended functions.

Reject Valves
Butterfly-/Shim valve EX-BF
for liquid and slightly pasty products, very stable, pre-opening on the discharge side prevents recoil into the pipeline, good price/performance ratio, CIP-cleanable, for pressure up to 16 bar
Arc valve EX-BOG
for viscous, pasty products or liquid products with solids, CIP-cleanable and free from dead spaces, suitable for cleaning with a pig, for pressure up to 40 bar
Piston valve EX-PWC
suitable for very tough or lumpy products such as sausage meat, internal piston lifts out of the product flow and deflects contaminated product parts, CIP-cleanable, for pressure up to 25 bar
Pressure hose
food safe, applicable up to 6 bar for steam with up to 164°C or 16 bar at 95°C water temperature, in all common sizes from 1″/25 mm to 4″/100 mm
Product pipe
made of polyoxymethylene (POM) for operating pressure up to 40 bar, in all common sizes from 1″/25 mm to 6″/150 mm
milk thread, Triclamp or SMS couplings
Simple version, without valves, with sealing cap (Triclamp) for inserting the test sphere, incl. test bodies
Testport Check & Catch
Tube with sealing cap for the insertion of a test body, additional rejection valve to ensure the flow of material during functional testing
Functional test that does not require opening the product pipelines: Test pieces (FE/NFE/VA) are moved through separate test tubes with compressed air. The control unit indicates which sphere sizes are to be tested. Including pushbutton for FE, NFE and VA testing, pneumatic valve, test piece.
Compressed air monitoring
Reports an error if the pressure is too low for the functionality of the rejection systems
Test balls
Test balls, diameter 10 mm made of plastic POM, with embedded metal ball made of iron, brass and stainless steel, certified, ball size, metal type and certificate number are embedded in the test ball
Other services
The SHARKNET® software connects METAL SHARK® metal detectors to a central computer and offers central storage of all operating data as well as batch and alarm documentation for HACCP and IFS conformity.
Increasing the IP protection type by adapting the sensor seal, installing additional seals and a double housing for the control electronics
Signalling devices (optical/acoustic)
Stacking lights and signal horns/sirens available in different versions and IP protection classes
Performance Verification Certificate
Performance Verification Certificate (proof of functionality for audits) by CASSEL service technicians possible, e.g. during commissioning or maintenance
