Low volume flowmeters are devices used to measure the flow rate or quantity of a moving liquid or gas. These flowmeters' measuring range typically include 0.25 - 1.5 and 10 - 80 l/h water and 20 - 80 Nl/h and 0.5 - 2.5 Nm3/h air. Specifications for low volume flow meters include pipe diameter, mounting style, end fittings, electrical outputs, and interface options.
