The MPB Series 1240S Dual Tube Flowmeter is suitable for applications where two process mediums are metered side-by-side. The inlet pressures ideally should be balanced. Where two flows converge, the MPB Series 1240S Dual Tube Flowmeter is ideal for this application. For instance, air and carbon dioxide, or oxygen and nitric oxide, etc, etc may be metered together as a compound gas (or liquid). Flow rates as low as 50cc/min Air, or gas equivalent and up to 150 L/min Air, or equivalent gas, can be employed where previously two individual flowmeters were used making neater presentation and space saving. Where extreme accuracy is required, this version of the MPB Series 1240 Dual Tube Flowmeter can be supplied with a single control valve with two flow tubes allowing a very low flow rate to cascade into a higher flow rate. This creates the opportunity to display very accurate readings across the required flow range (see 1241S MPBTB 101). The Series 1240S Dual Tube Flowmeter combines both flows into a common manifold and exits the compound flow through the outlet, which is positioned at the top right hand side of the flowmeter. However if preferred, two independent rear facing connections are required, MPB can accommodate this. An appropriate flame arrester must be employed where explosive gases are used.
