  • Vibrating Fork Level Switch for Solids and Liquids – DMS & DMT

    Vibrating Fork Level Switch for Solids and Liquids – DMS & DMT

    The Vibrating Fork Level Switch (DMS & DMT series) is the perfect completion of Delta Mobrey’s range of level detection solutions. This instrument completes the range of products for the control of level in tank, silos and pump protection. Solid products like grains or aggregate can be controlled with the Vibrating Rod (VLS), and the application can be expanded to granules and powders with the Vibrating Fork series.

    The same is also available for the controls of liquids, in combination with the Ultrasonic series 003 and all the mechanical float types.

    The vibrating forks are energized and kept in resonance by an electronic circuit. When covered by material, the damping of the vibration is detected by the electronics, which switch the output relay after a configurable time delay. The vibrating fork level switch is the perfect solution for single point level switching in free flowing solids and liquids across a wide density range, covering all the needs from industrial applications to the compactness requirements typical of the applications on machines.

  • Electrode for use with both Delta Mobrey’s Hydrastep and Hydratect systems, tested to withstand extreme pressures and temperatures.



    Electrodes are at the heart of our Hydrastep and Hydratect system.

    As well as being essential to the measurement of water and steam, they are also incredibly durable and reliable.

    This is due to their specific design, as each electrode is handcrafted and tested to withstand both extreme pressures and temperatures. As a result they can endure harsh conditions for many years (even decades), ensuring that your plant will continue to operate safely and consistently.

    For use with Hydrastep & Hydratect
