1. Introduction
KC-CMFI Coriolis Mass Flow Meters patented and developed by our company are the leading meters for precision flow measurement. And with good reason, KC meters offer the most accurate measurement available for virtually any process fluid, while exhibiting exceptionally low pressure drop. KC meters offer direct mass flow, volume flow, density, and temperature measurement of liquids and slurries — without the need for additional equipment, manual calculations, or estimations.
KC 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 KC meter is available with stainless steel wetted parts and a wide variety of process connections to meet your every need.
KC meters carry hazardous area approval for P. R. China.
2. Principles of Measurement
The structure of KC-CMFI 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.

4. Conditions required of installation
To guarantee the accuracy, conditions required when installation should be met, because the mass flow meter type of KC-CMFI is a high precision instrument:
(1) The sensor (primary meter) and the transmitter (secondary meter) do not install in strong magnetic interferential area. Or, measuring signals would be disturbed, and debase the accuracy;
(2) There is must not any other vibrator on line installed the sensor (primary meter);
(3) If install outside of door, PLS pay attention circumstance temperature not to exceed the range of meter, and should consider to build a weatherproof shield to avoid blowing and drenching, for increasing lifetime of flow meter.
(4) The transmitter (secondary meter) of essential safety should mount in safety area or appropriate control room.
(5) A shield cable with ten core lines connects the sensor (primary meter) and the transmitter (secondary meter) of essential safety.
The output cable of the transmitter (secondary meter) of composite is a shield cable with ten core lines.
Five meters long of the cable is normal option in package by our company. Customs can deal special order for longer cable, but not exceed 200 meters.
