BTL Series Level and Temperature Transmitter
The BTL series level and temperature transmitters are designed to measure both the liquid level and temperature within pressure vessels (up to 1.6 MPa). The product integrates both functions into a single unit, which is installed on the tank via a flange. It outputs two independent 4-20 mA signals for level and temperature to a control and collection system, reducing installation and wiring efforts.
