The PFA SonicLine ultrasonic flowmeter from Gemü is available in a low-fl ow version for quantities from 0.03-6l/ min in DN 3/8“. Flowrates from 0.5 to 1ml per second are achieved in the lower range for fi ne dosing of chemicals. The device measures 250 values/second and the reproducibility of the measured values is 0.5% with an accuracy of 1%. All medium-wetted parts are made of corrosion resistant high purity fl uoropolymer PFA-HP. There are no moving parts or instruments in contact with the media, minimizing pressure loss and contamination.
