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 computes the speed of sound in air, automatically compensating the Distance for temperature effects. The MSP400RH and MSP900GH have a Remote Temperature Sensor option. The distance measurement can be sent through the 4–20 mA or HART® output.
