About Ultrasonic Level Transmitters
Ultrasonic level transmitters measure level from the echo time of sound pulses, a cost-effective non-contact method for water, wastewater and chemical tanks. Seven Star LLC, an independent supplier in Muscat, supplies ultrasonic level instruments from ABB, VEGA, Endress+Hauser, Pulsar, Mobrey and Nivelco to customers in Oman and the GCC.
Types of ultrasonic level transmitter in this category
Compact transmitters such as the ABB LST200, LST300 and LST400, VEGA VEGASON 61 and Nivelco EasyTREK measure level in tanks, sumps and channels. Controllers like the Endress+Hauser Prosonic S FMU90 and Mobrey DMSP400 handle level, pump control and open-channel flow, and the Pulsar IMP+ is an intrinsically safe sensor for hazardous areas.
How to select a ultrasonic level transmitter
Define the measuring range, the medium, and conditions such as foam, vapour, temperature, dust and wind in open channels. Check the blocking distance at the top of the range, mounting position and beam angle. Specify output, relays for pump control and hazardous area approval.

Frequently Asked Questions
When is ultrasonic level better than radar?
For simple water and wastewater applications where cost matters and there is little vapour, foam or pressure.
What is the blocking distance?
A short zone directly below the sensor where it cannot measure. The maximum level must stay below it.
Can ultrasonic sensors measure open channel flow?
Yes. With a flume or weir, controllers such as the FMU90 calculate flow from the measured head.
What affects ultrasonic measurement?
Heavy foam, vapour, temperature gradients and dust can weaken the echo. Radar is better in those conditions.
What should I send for a quotation?
The model, or range, medium, application, mounting, output, relay requirements and quantity.
