Overview of the Mobrey MSP422/400RH/900GH Measurement principle The Mobrey MSP Series is a liquid level transmitter based on ultrasonic technology that is suitable for many liquid applications. Ultrasonic pulse signals are transmitted and reflected from the liquid surface. The transmitter ‘listens’ for reflected signals (echoes) and measures the time-delay between transmitting and receiving. The distance to the liquid surface is automatically calculated using the computed time-delay. An integral temperature sensor continuously measures the air temperature around the transmitter. It then...

Special features Advanced software features  Learn routine (false echo registration) The transmitter can learn to ignore up to four false echoes caused by the pulse signal reflecting off obstructions, until the actual level is seen. Empty tank mapping Remote Temperature Sensor Option (For MSP400RH and MSP900GH) When a tank is empty, the transmitter can learn to ignore up to four false echoes, without the need for user interaction.  Present depth The bottom reference can be automatically set using a known user-entered depth. Set as empty When the tank is empty, the bottom reference can be...
