Installation Diagram

The following drawing shows the recommended length of straight pipe section when installing the typical CL-2 product of CL series ultrasonic gas flowmeter. The installation shall comply with the relevant technical requirements of GB/T 18604.

Note: For uni-directional metering, the shortest front and back straight pipe segments can be configured according to thefront 3D and the back 2D; For bidirectional metering, both front and back straight pipe sections can be configured with aminimum length of 3D.

For flowmeters of PN16 pressure class, built-in temperature and pressure sensors are supported (customizable).

  CL-2 series ultrasonic gas flowmeter adopts two paths, path type is direct, measuring accuracy of 1.0 class, measuring bores cover from DN50 ~ DN500 (special specifications and larger diameter can be customized).
  CL-2 series products are suitable for metering of city gas distribution, high pressure gas storage, coal bed methane metering, Wellhead wet gas, flare gas, natural gas, raw material gas purification, separation and gathering and transportation treatment stations, petroleum and petrochemical and other large industrial users of gas process control and other metering applications.

  In the process metering application of city gas ring network, the flowmeter with bi-directional metering and higher IP class can give play to its unique advantages. For this kind of application, China Weise could provide CL-2 buried type ultrasonic gas flowmeter and CL-2 valve well type monitoring flowmeter.
