Remote Ultrasonic Level Transmitter TLTV1000A4

TLTV1000A4

TLTV1000A4 remote ultrasonic level transmitter is a non-contact level instrument with separate meter and probe installation. It uses ultrasonic time-of-flight technology with real-time temperature compensation to measure liquid level from the echo return time. Also, it supports measuring range up to 40 meters, 4-wire configuration, 4 relay outputs, HART, RS485 / Modbus-RTU digital interface, LCD keypad operation, six display modes, ABS housing and probe cable length up to 200 meters. As a result, it suits tank, sump, wastewater and process vessel applications where remote display and digital communication are required.
