Explosion Proof Ultrasonic Level Transmitter


Tek-Sound 4200A Explosion Proof Ultrasonic Level Transmitter is commonly used level measurement instruments demanded across industries for the continuous measurement of the levels and volumes of different media in open and closed tanks and for flow measurement in open channels. They are a cost-effective, reliable, and accurate solution that can be used in a wide array of applications involving both solids and liquids. Since they are non-contact devices, they require minimal maintenance and suffer minimal wear and tear; Additionally, this also ensures that they can be used under difficult process conditions.
