Ultrasonic level transmitter
4–20 mA | ECHOTEL® MODEL 300/301
MAGNETROL
The Echotel Model 300/301 is a full-featured, powerful ultrasonic transmitter for measurement of liquid level, volume, or open-channel flow. Explosion proof approvals are standard for both the transmitter and transducer.
Ultrasonic pulses are emitted from the transducer and the time required for the echo to reflect from the liquid surface and return to the transducer is measured.
