Gas Turbine Flow Meter – Overview

The Gas turbine flow meter is a new generation of high-precision and high-reliability gas measuring instruments. It has excellent low and high-pressure metering performance, various signal output modes and low sensitivity to fluid disturbance. The Gas Turbine Flow Meter boasts advanced rectification technology and a dust-proof structure. It includes built-in temperature and pressure sensors which automatically compensate to ensure high accuracy.  This gas turbine flow meter is used with low pressure loss, and low initiating flow and has a wider measurement range than the other flowmeters in this series. The display can rotate 350°, making it easy to read data in different directions. Applications include natural gas, LPG, coal gas etc. Widely used in various industries of gas metering and gas pressure regulating stations such as petroleum, chemical, electric power, industrial boilers, gas transmission and distribution pipeline networks, and urban natural gas metering.
