Introduction of mass flow meter
Mass flow meter consist of mass flow sensor and mass flow transmitter. It does not measure the volume per unit time (e.g., cubic meters per second) passing through the device, but measures the mass per unit time (e.g., kilograms per second) flowing through the device. The result of volumetric meter varies with temperature, pressure, composition, etc., but mass flow meter does not have such problem.
Application of mass flow meter
The Sealand Coriolis Flow Meter family measures direct mass flow rates of liquids and gases in virtually all applications without special calibration. Safety, reliability, quality, and our innovative technologies enables us to provide a broad range of industry-specific products and services — and the expertise to put them to work for you.

Dimension of mass flow meter
Advantages of mass flow meter
1. High reliability
2. It requires low maintenance, because of no movable parts.
3. High accuracy: Generally, it is from 0.15%-0.3%.
4. It is not affected by the fluid, saving the design & installation cost.
5. It shows many parameter simultaneously, such as mass flow, temperature, density, etc.
Installation of mass flow meter
It is highly recommended to install as follows, for different fluid.
Production process of mass flow meter
1. Bend vibrating tubes with bending machine
2. Smear the solder on the production line
3. Solder the tubes in the Vacuum brazing furnace
5. Test for the 1st time
6. Burn-in: Mass Flowmeter will be excercised for 15 days prior to being placed in service.
7. Test for the 2nd time (at the same production line of step 5)
8. Cover the tubes with housing & polish the surface (at the same production line of step 2)
9. Test for the 3rd time(final test; this test equipment is approved by China government, and is the
TEST STANDARD of mass flowmeter in China)
