Description
They are designed to measure the volume of natural gas, liquefied gas vapors, and other non-aggressive gases. The principle of operation is based on the dependence of oscillation frequency to measure gas flow rate. The oscillations of the flow are converted by a piezoelectric element into an electric pulse proportional to the volume of gas. This signal is then converted in the electronic unit into the value of the gas volume and recorded as total.
Available according to EN 1359.
