SUP-MP Ultrasonic Level Transmitter
The SUP-MP is a non-contact ultrasonic level transmitter with selectable ranges up to 30 m, used for water and wastewater tanks, sumps and open channels. Output options across Supmea's ultrasonic range include 4–20 mA, RS485 Modbus RTU, HART and relay alarms; the exact combination depends on model. Choose radar when vapour, foam or temperature layering is present.
What it does
An ultrasonic transmitter sends a sound pulse and times its echo from the surface. It is simple, low-cost and easy to mount, which makes it the workhorse for water tanks, pump stations and flumes.
For sludge blanket measurement under water, Supmea's SUP-JFC ultrasonic mud level transmitter covers interface ranges up to 20 m.

Frequently asked questions
When should I choose ultrasonic over radar?
For clean water applications at atmospheric pressure where cost per point matters. See our radar vs ultrasonic comparison.
Can it measure open-channel flow?
Yes, when combined with a Parshall flume or weir and the matching level-to-flow curve.
