title
Endress+Hauser recently released the Proline t-mass 150 thermal mass flowmeter for measuring gases, such as compressed air, nitrogen, carbon dioxide and argon. According to the company, the t-mass 150 also furnishes:
- The measurement of mass flow, gas temperature, free air delivery and corrected volume — all without the need for pressure or temperature compensation.
- The capacity to measure mass flow up to 2.4 million pounds/hour with negligible pressure loss.
- The ability to reliably measure small gas quantities at very low operating pressures.
- A Gas Engine — embedded flow computer — that makes it possible for the flowmeter to change from one gas to another without the need for recalibration.
- Continuous self-diagnostics to monitor the device and for process errors.
- Operating temperatures from -40º to 212ºF (-40º to 100ºC) and pressures up to 580 PSI (40 BAR).
- A pulse/frequency switch output, allowing easy connection to control and energy management systems.
- A 4- to 20-mA output with HART.
- A high turndown ratio of 100:1.
- Stainless steel construction.
- Compliance with CSAus and approvals for use in Class 1, Div. 2 areas.
- Availability in insertion, in-line or hot-tap versions for installation in rectangular ducts or pipes from 1/2 to 60 inches.
- Selection from welded flanges, lap-joint flanges or threaded connections.
- Suitability for applications that include leak detection, process control, cost allocation, analysis of flow profiles and energy management.
