Gas Turbine Flow Meter
Product Overview
Gas Turbine Flowmeter combines gas mechanics, fluid mechanics, electromagnetism and other theories to develop a new generation of gas precision metering instruments, excellent low pressure and high pressure metering performance, a variety of signal output methods and low sensitivity to fluid disturbance, widely used in natural gas, coal gas, liquefied gas, light hydrocarbon gas and other gases measurement.
Characteristics
The turbine flow sensor and display integral intelligent instrument developed by gas turbine Flowmeter are developed by low power single chip microcomputer technology. the double row liquid crystal field display has many obvious advantages, such as compact mechanism, intuitionistic and clear reading, high reliability, no interference from external power supply, anti-lightning and so on. The instrument coefficient is corrected by six points, and the instrument coefficient is nonlinear by intelligent compensation, and it can be corrected on the spot. A clear liquid crystal display displays both instantaneous flow (4-digit valid numbers) and cumulative flow (8-digit valid numbers with zeroing function). Do not lose valid data for 10 years after power down. Explosion proof grade is: ExdIIBT6.
