Description：
ZW - LA seriesThread link gear flowmeterIs one of the volumetric flowmeter, used for precise measurement for continuous and discontinuous flow or instantaneous flow of liquid in the pipe.It is especially suitable for heavy oil, polyvinyl alcohol, resin and other high viscosity medium flow measurement.
Second, the working principle and structure:
ZW series - LA thread link gear flowmeter cavity in the body has a pair of meshing gears as the rotor to each other, the two gear with cavity can constitute a fixed volume, respectively, referred to as the standard volume and flow rate is calculated to a flow within a certain time the number of standard volume measured.Two gear precision with closed in a strong cavity in the body of work, measured liquid drive gear rotating, the non-contact detector gear rotation.Gear gap formed between the measuring chamber.Each tooth after detector, detector to produce a pulse.Of the output pulse signal by the instrument volume/pulse (Vm) conversion and processing, display reading to meet the requirements of users.This flowmeter especially suitable for precision, high pressure, high viscosity in the environment.

Applications:
ZW series - LA thread link gear flowmeter is widely used in petroleum, petrochemical, natural gas, chemical industry, papermaking, automobile, food and other industries, also is used to measure the tiny flow measurement of small diameter.
Four, the main features:
1, the flow measurement has nothing to do with the flow of the fluid;
2, the greater the viscosity of the medium, from gear and measuring the less empty clearance leakage of the leak out, therefore the greater the viscosity of the measured medium, the more you small leakage error, good for measuring the;
3, high measuring accuracy, suitable for high viscosity medium flow and measure, but is not suitable for fluid containing solid particles, need to add the filter;With a gas, such as medium can also cause measurement error;
4, small volume, light weight, small vibration noise when running, can measure the viscosity is as high as 10000 pa. S fluid.Measurement accuracy of 0.5, 0.2 on the Richter scale are unlikely.Wide measuring range zui up to 50:1;
5, have a general-purpose, high pressure, food, etc, are suitable for all kinds of cleaning liquid of small flow measurement.
Five, the technical parameters:
