Name：Clamp-on Ultrasonic Flow Meter
Model：LRF-3300SW
Size：254*230*64mm
General Introduction：
LRF-3300S is a wall-mount, clamp- on type ultrasonic flowmeter which use the transfer time technology. Clamp on type ultrasonic flowmeter is easy to install and no need to cut off the pipe, that saves you lots of troubles and cost. At the same time
LRF-3300S has our unique calculate software to ensure the high accuracy and low velocity response. LRF-3300S could add the RTD model and temperature sensor become an energy meter to monitoring the energy use, help to save the energy.
