The MPB Series 3000 range of Variable Area Flowmeters from HMA INSTRUMENTATION is an economic means of accurate flow measurement. A 260 mm scale length offers excellent resolution, providing easily-read scale graduations. The range can handle flow rates as low as 50 cc/min air. The flow tubes utilise a ‘free float’ design, which has a very low pressure drop. The MPB Series 3000 from HMA INSTRUMENTATION is an ideal flowmeter for use as a calibration master, or where high accuracy with a good resolution scale is required, especially for the most demanding of variable area flow.
