We manufacture a full range of variable area and calibrated flange flowmeters allowing for a vast application for small and high liquid and gas flows. The variable area flowmeters have a perfectly calibrated borosilicate glass gauge with a stainless steel or plastic body, or are totally manufactured in stainless steel or in plexiglass. They are available in threaded or flanged version. Accessories: minimum and maximum flow alarms and 4 - 20 mA standardised signal at output, proportional to the flow.
