■Product Ioduction

LC series oval gear flowmeter is the main products of our company. LC oval gear flowmeter is one of the typical displacement meter, used for measurement of pipeline fluid flow under certain pressure. It has a simple structure, reliable use and high accuracy, flow field has no special requirements for import and export of the pipe, the viscosity of the measured medium range and the characteristics of the flow range is very wide. And therefore is widely used in petroleum, chemical industry, medicine, transportation, food and other industrial and commercial sector of liquid flow detection. Lc series oval gear flowmeter is particularly suited to the measurement of oil fuel.

  In order to meet market and customer demands, HeFei Walrus Instrument company, combined with 10 years manufacturing experience, continuous improvement and innovation, ioduced in different environmental conditions are suitable for the use of elliptical gear flowmeter products. , Light-weight oval gear flowmeter, high-temperature type oval gear flowmeter , high-viscosity oval gear flowmeter, electronic displayoval gear flowmeterand etc.

■Working principle

In the measuring chamber, a part of oval wheels and cover plate make a fan shape city which is used as a measuring element. The oval wheels are rotated by the little pressure difference in the inlet and outlet of the meter and drive the inlet liquid through the city to the outlet, each revolution of the oval wheels displaces fluid four times the volume of city, the total revolutions of the oval wheels and revolutions rate will be transferred to the counter.

■Flowmeter piping method

⑴A filter should be installed in front of the meter, and be sure that the arrow on the ting of the meter and filter pointing the same direction of the liquid flow.

⑵Whether the pipe line is vertically or horizontally installed, the wheel’s shaft of the meter must be fixed horizontal, that is ,the dial is vertical ti the surface.

⑶Pipes to the installation of the meter, the pipe must be throughly cleaned.

⑷While the meter is installed properly, the counter may be turned 180° or 90° for easy reg.

⑸A regulating valve must be fixed at the of the meter, a shutoff valve at the outlet, the valve must be slowly opened to prevent from a sudden impact, and water hammer.

⑹It is forbidden to clean the meter with steam.

⑺For the continuous operating department, a bypass should be mounted.

⑻The filter should be cleaned out of impurity to prevent from blocking, the meter should be tested and overhauled in a fixed period.

 Flow Meter Installation MethodCompany

⑴ The flow meter arrow is installed according to the flow direction of the liquid (it is recommended that the display surface of the flow meter should be perpendicular to the horizontal plane).

⑵ Open the four screws ① on the cover ring, remove the glass and facial mask, unscrew the four screws ② on the electronic mainboard, and the electronic mainboard can rotate by 90 °, 180 °, 270 ° according to itself.

⑶ Reinstall the screws and install the facial mask, glass and cover ring.
