OPEN CHANNEL FLOW
MSP900FH ultrasonic level transmitter for use in open channel flow measurement has a pre-wired remote temperature sensor and is suited for use in water and processing sites. Measuring 10mm diameter x 25 mm length, the sensor can be located in an appropriately shady spot between the liquid surface and the transmitter. In this way, the system ensures that the air temperature measurement used in speed of sound calculation is truly representative. The transmitter is 24 Vdc loop powered, supplied in a waterproof housing sealed to IP68. It has both analog 4-20 mA communications and digital HART options built-in, and can be used stand-alone, or as part of a site-wide measurement, control and data acquisition system.
