Levelling Up Liquid – The Bubble Level Measurement System

Some industrial environments have harsh conditions – in the petrochemical manufacturing process, liquids can be extremely corrosive, damaging liquid measuring equipment. In other sectors, such as water treatment, sampling parts designed to test fluid safety can be prone to plugging, causing difficulties during analysis.

In these situations, the Bubble Type Level Measurement System comes in. It handles highly corrosive fluids, as well as benefitting users with a low-cost installation that provides long-term saving during its lifetime of operation.

Bubble level measurement system – how it works

The system works by using clean air to measure the amount of pressure it takes to push air bubbles out of a probe tube into liquid within a tank. As the liquid level in the tank varies, so does the pressure needed to emit bubbles from the tube. These variations are detected precisely by our pressure transmitter, giving a signal output in proportion to the liquid level.

Products for integration with the bubble level measurement system

Our D Series pressure transmitters can be easily integrated into the Bubble Level System to ensure an accurate reading. For measuring liquid in an open atmosphere tank, we would recommend the D21 Pressure Transmitter. For a pressurised tank, the D31 Differential Pressure Transmitter is recommended. Both benefit from an easy set-up and can be configured either using a standard HART communicator or using Delta Mobrey’s D-Soft communication software. Both feature an accuracy of 0.075% as standard, though depending on your application we can provide even greater accuracy.

Besides the D21 & D31 transmitters, we can also provide other Bubble Level System components or even the entire system itself. Our Bubble Type Level Measurement System datasheet can be viewed here.
