Ultrasonic gas flowmeter ARG—31.2 with piezoelectric transducers PPW-33/2A is designed to measure the volumetric flow rate and gas volume (dry / wet blast furnace, coke oven, air and other technical gases, including under adverse conditions, moisture condensation and the volatile fractions). The flowmeter can include additional options: two current inputs (for pressure and temperature sensors) and a built-in calculation of gas consumption to standard conditions and the volume of gas passing through the meter.
For equipment delivered to the CU countries, this options are enabled by the software.
The number in the State Register of Register of Measurement Equipment Units is U1711-04 in Ukraine, 31799-06 in Russia. Approved methods provide dry calibrated flow meter. They allows to calibrate without having to remove the transducers, without process interruption (if it's necessary).
Flow meters are equipped with explosion-proof transmitters PPW-33/2A with active frost protection function (A). The main purpose is preventing the growth of ice, resins and naphthalene on the measuring elements in the wet blast furnace and coke oven gas at low temperatures and the inevitable variations in process technology. This is an effective certified technology maintaining the temperature of the measuring element.
