Name:Insertion-type Ultrasonic Flow Meter

General Introduction:
LRF-3300S is  a fixed type ultrasonic flowmeter which use the transfer time technology.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.It uses the latest digital technology and low-voltage broadband pulse transmission. The instrument is tolerant of liquids with small amounts of air bubbles or suspended solids found in most industrial environments. With distinctive features such as high accuracy, high reliability, the MPU in the instrument provides unique digital signal processing and a relevant test programs. This flow meter provides long-term no-drift measurements and sorts the operating software to adjust parameters according to changing conditions.
