All the flow tubes utilise a ‘free float’ design which has a very low pressure drop. The MPB Series 3000 is an ideal flowmeter for use as a calibration master, or where high accuracy with a good resolution scale is required for the most demanding of variable area flow applications. The materials of construction offer compatibility to a wide range of industrial process mediums. The units are fitted with a calibrated scale plate.  In addition, a metric scale is permanently fired onto the tube.  A useful blank scale plate can also be provided for customers own calibration if required. The MPB Series 3000 Flowmeter can be used to measure the flow rate of most process gases and liquids. One or two economical latching Hi and Lo alarm devices can be fitted.  These enable the alarms to remain activated whilst flow is above or below a set point.  This reduces expensive electronic circuitry and is ideal for remote and process control applications.]]> Features
