Mass flow meter for CNG fueling system

Product Overview

Description

 

Introduction of CNG mass flow meter

Mass flowmeter consist of mass flow sensor and mass flow transmitter. It does not measure the volume per unit time (e.g., cubic meters per second) passing through the device, but measures the mass per unit time (e.g., kilograms per second) flowing through the device. The result of volumetric meter varies with temperature, pressure, composition, etc., but mass flowmeter does not have such problem.

 

Operating principle of CNG mass flow meter

Mass flowmeter is designed according to Coriolis Effect. The inlet arm and the outlet arm vibrate with the same frequency as the overall vibration, but when there is mass flow the two vibrations are out of sync: the inlet arm is behind, the outlet arm is ahead. The two vibrations are shifted in phase with respect to each other, and the degree of phase-shift is a measure for the amount of mass that is flowing through the tubes.

 

Sealand CNG-015 mass flow meter

Sealand CNG-015 Compressed Natural Gas meters are specifically designed for the CNG fuel 

dispensing industry to meet the challenges of measuring compressed natural gas for custody 

transfer. With worldwide installations, the CNG-015 is the preferred meter of the leading CNG 

dispensing equipment manufacturers.

 

Feartures:

*Reduced fill time with higher flow rate capacity

*Compact design with no moving parts, no special mounting and no flow conditioning required

*Fast delivery and global support
