• LC-L series heat preservation jacket oval gear flowmeter
  To facilitate easy to solidify or freeze, or under a certain temperature condition, often cooled crystals media reaction in the pipe temperature and temperature monitoring, need to heating system of the pipeline medium, medium heat and heat preservation. Because the oval gear flowmeter installation place is not allowed to pass the steam (steam) to prevent damage meter, therefore we design oval gear flowmeter with insulation jacket products, which outside the meter shell increase insulation jacket, make heat 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 flange design, special requirements can also design the user interface. Heat preservation jacket nominal pressure 0.5 MPa, can also be adjusted according to customer special requirements.

• LC-Dseries mechanical quantitative oval gear flowmeter
