The meters are designed for unsurpassed performance in even the harshest operating environments. They have no moving parts, and any special mounting or flow conditioning requirements. Every meter is available with stainless steel wetted parts and a wide variety of process connections to meet your every need.
Principles of Measurement:
Coriolis Mass Flow Meters was consisted of a pair of bended tubes. The principle is to detect Coriolis force forced a pair of tubes from inner mass flow by fluid.
A new force-Coriolis force would be appear while two conditions met: (1) vibrating with normal frequency in a pair of bended tubes, (2) fluid flowing in tubes. This force was produced upon synthesis from vibrating force and flowing force by fluid in tubes. And tubes would be wresting symmetric the center line because the force forced. Two displacement sensors on sides of tubes detect the force and output electric signals. The signals regulated, mass flow directly produced.
-Using the world's most advanced second generation transmitter technology - DSP technology, higher precision, wider range, more simple structure, more stable operation.
-Measurement of high pressure gas (such as CNG compressed natural gas (LNG), low temperature liquids such as liquefied natural gas, liquid nitrogen).
-Using high-precision processing technology, ensure the sensor quality, zero stability.
-Using digital signal processing (DSP) technology, metering system host through the 485
communication, the relevant parameters, to obtain the required such as: mass flow, volume flow rate,temperature, density, the state information.
-Through the debugging software or manual debugging device can read the fault code, solving the problem of inconvenient meter using the staff more comprehensive, troubleshooting
-Support the standard industrial control communication protocol ModbusRTU, easy configuration and use.
-According to user needs, mass flowmeter in design and manufacture of special specifications and has special function, tailored to the user.
