Capacitance limit detection in fish oil

Easy installation and automatic calibration

A fish feed manufacturer based in Denmark was looking for a consistently precise, yet simple, user-friendly level monitoring for its fish oil storage tanks. In addition to being used as a lubricant, leather tanning and, due to its omega-3 fats, as a food supplement, fish oil is mainly used in the manufacture of pet food and for aquaculture. Fish farming, as a rapidly growing global industry, necessitates plant operators to continuously optimize their production technologies and processes. In the storage processes, the robust, capacitive RF rod probe proved to be the optimal solution for the fish feed manufacturer thanks to the precise surface detection and automatic calibration capabilities of the device.


Precise overfill protection unaffected by foam

The DK value of the fish oil to be measured is in the range 2.0 - 3.0. In order to avoid container overflow, a reliable measurement is crucial for the application, taking into account the frequent formation of foam during filling. The installed RFnivo® sensor with a length of 750 mm and a probe made of 1.4404 stainless steel proved to be a process-compatible solution for monitoring oil storage. The integrated "Active Shield" technology as standard in the RF probe also ensures that the measurement result is not influenced in the long term by buildup or foam. By equipping the total of 6 tanks with a reliable full monitoring system, permanent protection against overfilling of the fish oil tanks could be guaranteed.  This in turn ensured optimal support of a smooth and maintenance-free manufacturing process for the fish feed manufacturer.

Precautionary measures coronavirus

We are aware of the situation and have implemented necessary measures!

The novel coronavirus (SARS-CoV-2) is now also spreading in Germany and the numerous reports in the press and the many new infections in Europe show us that the disease is becoming more prevalent and that the situation cannot be ignored.

We would therefore like to emphasize that we are extremely aware of this new challenge and that we are already intensively working on many precautionary measures.

For example, we have significantly increased our stocks of "critical parts" and distributed them among our locations in Malta and Betzigau. Ensuring sufficient safety stock and having backup solutions in place will ensure that both our warehousing as our sensor assembly will not be effected. Furthermore, we are in very close contact with our suppliers and regularly exchange information about the current situation in their plants and the rest of the supply chain.

From today's perspective, we therefore do not foresee any delays in the delivery of our point level and continuous measurement sensors. However, if there are any changes, we will inform you immediately.
