Endress+Hauser's Proline t-mass 150 Flowmeter is built for gas flow measurement
Endress+Hauser's Proline t-mass 150 thermal mass flowmeter is built to measure mass flow, gas temperature, free air delivery and corrected volume without the need for pressure or temperature compensation.
The t-mass 150, with its turndown of 100:1, is designed to measure small gas quantities at low operating pressures. It has a 4-20 mA output with HART and a pulse/frequency switch output. The flowmeter is engineered to operate in temperatures from -40 to 212º F (-40 to 100º C) and pressures up to 580 psi (40 bar), and measures mass flow up to 2.4 million lb/hr with negligible pressure loss. The stainless steel flowmeter has CSAus and ex approvals for use in Class 1, Division 2 areas.
The t-mass 150 has a Gas Engine — an embedded flow computer — that makes it possible for the flowmeter to change from one gas to another without the need for recalibration, and its thermal measuring principle requires no pressure or temperature compensation.
