MTX & WPX Turbine Flowmeter
Brand: Niagara Meters
Liquid enters a precision metering insert containing the turbine rotor.
The liquid pressure drives the turbine rotor rate of rotation proportional to the volumetric flow rate.
The rotor’s rotation is magnetically coupled to a hermetically sealed indicator of indicator/transmitter.
Features- Saves space: very compact size, lightweight
- Flexible and unique design: add pulse transmitters without downtime, modular construction allows ease of service and field repair, power not required for mechanical version
- Reliable: sealed register prevents condensation or fogging, one internal moving part
