Series 640S and 1040S Dual Tube Variable Area Flowmeters

GENERAL INFORMATION

The MPB Series 640S and 1040S Dual Tube Flowmeters are designed for measuring two instantaneous flow rates of virtually any process liquids or gases simultaneously.  The principle of operation of the flowmeter is quite simple:-

The height attained by the float in its tapered flow tube is directly related to a calibrated scale.  The flow should be read from the centre of the ball, or top of a plumb bob float.

This flowmeter offers very low flows down to 2-20cc/min (Air).

The MPB Series 640S and 1040 Dual Tube Flowmeters have rear facing connections as standard and the flowmeters are supplied complete with 2 x M4 mounting studs.

Whilst MPB Industries supply an extensive range of standard flow tubes, MPB can design and manufacture flow tubes for virtually any gas or liquid and calibrate for a wide range of process conditions (please contact our sales office).

 For increased flow rates and higher scale resolution, please see our technical literature MPB Series 1240S (technical bulletins MPBTB 100).

Typical applications include analytical instrumentation, gas flow control, small dosing systems, purge metering, leak detection and blending systems, or any requirement for a dual tube arrangement.

Typical industries served include brewing, gas analysis, aerospace, pharmaceutical, engine testing, paper, water treatment, oil and gas, etc.
