The Delta Mobrey DMSP422 DMSP400 and DMSP500 Series is a liquid level transmitter based on ultrasonic technology that is suitable for many liquid applications. Integral LCD display with push button controls and menu greatly simplify configuration and diagnostics. An internal temperature sensor compensates for temperature affects. The level, contents or flow measurement is available on the 4–20 mA and HART output. May be used with the DMCU900 HART® controller for local display and complex pump control.
Ultrasonic pulses are transmitted to and reflected from the liquid surface. The measured ‘time-of-flight’ determines the distance to the surface. By configuring the distance to the bottom of a vessel, the transmitter can calculate the liquid level and contents (volume) for linear or non-linear vessels (domed, spherical, etc). For open channel flow, the transmitter can calculate the flow rate from the level for a wide variety of flumes and weirs.
