1. Introduction
Coriolis Mass Flow Meters patented and developed by our company (Chinese Patent No. 03119685.3, 03149996.1) are the leading meters for precision flow measurement. And with good reason, the meters offer the most accurate measurement available for virtually any process fluid, while exhibiting exceptionally low pressure drop. The 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.
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.
The meters carry hazardous area approval for P. R. China.
2. product main performance characteristics
l It can directly the mass flow rate of the pipe.
High accuracy, good repeatability, can measure the mass flow in a widely range.
l High measurement accuracy.
This measurement accuracy grade is 0.2.
l high reliability and wide range application
As there is no barrier and moving parts in the measurement pipe, with advantages of high reliability and long service life.
l Adopted fluid surface width.
In addition to the uniform fluid, it also can measure high viscosity fluid (bee honey, slurry etc.), as well as multiphase flow. No matter medium are static flow or turbulent flow, what ever influence the measuring accuracy.
l widely application environment
Applicable to petrochemical, chemical, metallurgical, pharmaceutical, paper making, food, energy and environmental protection and other industries.
l a variety of on-line measurement functions
In addition to mass flow, it can directly measure the density and temperature of the fluid. The intelligent flow transmitter is a kind of multiple functions flow measurement instrument, which can offer display and control of many parameters.
l good scalability
According to your consumers required, we our company had designed and made special specification models and functioned mass flow meters, but also for remote monitoring operation, etc.

4. Installation, Adjustment and Operation
The transmitter (secondary meter) of composite type mounts on the sensor (primary meter) with attached screws. A shield cable connects two parts.Installation of the sensor shows in Figure 6, illuminate hereinafter now:
(1) The mass flow meter normally installs in level line, main body perpendicularity downwards. PLS pay attention to the direction label on flow meter, should be same as the direction of fluid in line. If can not confirm direction, PLS see Figure 6 and 10, while the cable socket on back of the mass flow meter, flow direction is from left to right;
(2) Securing supports should be built in upper and lower reaches of a line beside the flow meter;
(3) Ensure concentric with two flange of flow meter and line while installation. When screwing, screws should be forced uniformity symmetrically, do not impose contraposition, forbidden wring or bend the primary meter;
(4) Definite back pressure should keep in lower reaches of a line behind flow meter. Do not let line direct open, prevent incorrectly measure while half tube of liquid;
(5) The sensor (primary meter) must leave up ground, and do not touch anything;
(6) The tube of upper reaches of line must equal or large than the meter’s inner diameter, forbidden to less than;
(7) The body of sensor should be covered with heat preserved material, for measuring the liquid that easy gasifies. Or, the sensor may be damage with frost or dew;
(8) For type of DN1, DN3, DN6 and DN10, the sensor should install on ground, use soft tube to connect to the lines;
(9) The serial number of sensor and transmitter should same, if the serial number not match, the error may be bigger than normal
