diaphragm gas meter
●anti-reversal design prevents reverse gas flow effectively.
●separate diaphragm and upholder; precise metering and stable performance.
●adjustable core and clear mechanical design to ensure accurate measurement
●magnetic drive technology applied to ensure the safety and reliability.
principle
within the meter, there are four chambers divided by two diaphragms. the diaphragms moves alternately while the gas flows as different pressure occurs within the four chambers. the gas flow will be calculated after a series of transmission, speed shifting mechanism and will be displayed on counter finally.
key technology
anti-reversal gas flow, separate diaphragm and upholder, adjustable mechanical core, base shell without plug, compound flagpole design.
