Flow Detection

We offer a comprehensive range of flow measurement solutions for closed pipes, open channels and partially full pipes.

From the flowmeter to the supply of complementary readouts, control units and differential pressure transmitters, we have a wealth of experience.

Level Detection

Most liquid storage tanks have some type of level indication. These gauges perform a vital role in indicating the contents level, and in some cases actuating low or high level alarms.

We select equipment from a range of leading manufactures to ensure that we provide a tailored solution to your requirements, that is accurate, reliable, efficient and cost effective.

Marine Level Solutions

We supply a comprehensive range of instrumentation and controls for the monitoring and control of liquid level in the marine industry.

The equipment we supply is tried, tested and internationally approved for use on all types of ships and offshore installations.
