Measuring the Future
Greetings!
With multiple instruments suitable for a wide variety of applications, we've got you covered when it comes to precision water level measurement for surface water, groundwater and water storage applications. Whether its our Radar Level Sensor with 2mm accuracy, Bubbler sensing systems that never require dessicant, 'no drift' Submersibles and Shaft Encoders with dual data outputs...you'll find an instrument to suit your specific application.

Non Contact Radar Level Sensor
Can it really be that good? That answer is a resounding yes! Just ask the thousands of customers who have used them in a multitude of applications all over the world. These new generation radar level sensors have superb accuracy (+/-2mm), ample measuring range (up to 246 ft) and a recorded mean time between failure (MTBF) of over 50 years.


HS-40 Compact Advanced Bubbler System
Meticulously engineered to deliver reliable, trouble-free operation, year after year, even in the harshest possible environments. No moisture issues or dessicant to recharge means greater reliability, a reduction in unscheduled site visits and cost savings overall. Our latest model, the HS40 'Compact' incorporates the most valued features of earlier models whilst setting a whole new standard in performance and price.


AD375MA Shaft Encoder
The AD375MA/AD100MA absolute Shaft Encoders are low powered, microprocessor controlled devices, suitable for reliable and accurate sensing of water level. Dual Data Output 4-20mA/SDI-12, integrated mount, robust construction and easy to configure backlit display with user adjustable metric or imperial output.

Hydro-Well Submersible
Designed for continuous level measurement of liquids with typical applications including surface water, waste water, deep wells and in the shipbuilding industry.

The ceramic CERTEC measuring cell is the heart of the Hydro-Well. The hydrostatic pressure of the liquid column causes a capacitance change in the measuring cell via the ceramic diaphragm. This change is converted to a standard 4...20mA signal. The entire measuring cell consists of high purity ceramic, renowned for its excellent long-term stability and very high overload resistance.
Leaders in Water Level Measurement
2019 marks our 21st year in the industry and the business philosophy which has guided us all these years has never been more important to us:

  • We stand behind every product we sell
  • You will never be left alone with a product that is not performing
  • Relationships take priority over profit

We are proud to introduce you to our extensive line of Level Measurement Sensors...and hope you'll consider us for your next application.
