LC-U series heat preservation jacket oval gear flowmeter
To facilitate easy to solidification of room temperature, or under a certain temperature condensation, easily crystallized media normal reaction in the pipeline transportation and traffic monitoring, often need to heating system of the pipeline medium, medium melt and heat preservation. But because the oval gear flowmeter installation place is not allowed to pass by steam (purpose is to prevent damage meter), therefore we design oval gear flowmeter with insulation jacket products, which outside the meter shell increase insulation jacket, make has solidified medium melt flow meter, and maintain a certain temperature, so as to ensure the normal operation of flowmeter. Oval gear flow meter installed in front of the filter can also adopt the structure of insulation jacket. Heat preservation jacket in and out of the structure, generally according to DN15 caliber flange design, special requirements can also design the user interface. Heat preservation jacket nominal pressure is 0.5 MPa, can also be designed according to customer special requirements.

●LC-D series mechanical quantitative oval gear flowmeter
LC – D type mechanical quantitative oval gear flowmeter (hereinafter referred to as the flowmeter) is a special flow meter, it is composed of oval gear flow meter, reducer and quantitative counter of three parts, can accurately measuring the cumulative amount of the liquid, when the number to the expected value, shut automatically turn on the electric circuit control valve, thus satisfies the requirement of flow metering control.
