Mechanical diesel flow meters have been designed for precise measurement of the quantity of fuels dispensed for non-commercial use. Easy to calibrate and install, the K33 and K44 flow meters can monitor the quantity dispensed for a maximum flow rate of 20-120 l/min and with a maximum working pressure of the pump of 10 bar. In addition, they can guarantee a burst pressure of 30 bar with a metering accuracy of +/- 1%.
