Endress+Hauser 65F15-AE2AG1AA Proline t-mass 65F Thermal Mass Flowmeter
An inline thermal mass flowmeter configuration for industrial gases and compressed air.
Overview
Endress+Hauser 65F15-AE2AG1AA belongs to the Proline t-mass 65F inline thermal mass flowmeter family. The 65F platform measures gas mass flow directly and can also provide temperature, volume-flow and energy-flow values.
The 65F15 code identifies the DN 15 inline size. The remaining ordering characters define the configured process, transmitter, output and approval execution and must be matched from the complete device nameplate.
Specifications
Features
Direct gas mass-flow measurement without a separate pressure or temperature compensation calculation.
Inline sensor construction for small line sizes and industrial gas services.
Integrated gas configuration supports defined gases and gas mixtures within the device capability.
Local display and operating-tool access support commissioning and service work.
Applications
- Compressed-air monitoring and utility-gas accounting in industrial plants.
- Flow trending for process gases and defined gas mixtures in DN 15 piping.
- Energy-flow monitoring when the configured transmitter and gas data support the calculation.
- Like-for-like replacement where the complete 65F15-AE2AG1AA nameplate execution is retained.
Lifecycle
- The t-mass 65F is no longer available as a current product; Endress+Hauser lists t-mass F 300 and F 500 as successor families.
- A successor migration requires a fresh review of process connection, straight-run requirement, outputs, hazardous-area approval and configuration data.
- Before removal, save the device configuration and record the flow direction, installation orientation and existing wiring.
- After installation, verify the configured gas, reference conditions, engineering units and zero-flow behavior before accepting the measurement.
FAQ
Is 65F15-AE2AG1AA still a current Endress+Hauser product?
The t-mass 65F family is discontinued. Availability should be handled as a legacy spare or a migration project rather than assumed current production.
Can a t-mass F 300 replace 65F15-AE2AG1AA without engineering work?
No. The successor family has a different platform and must be selected against the process connection, gas, pressure, temperature, outputs, approvals and available installation space.
What nameplate information is needed for a 65F15-AE2AG1AA quotation?
Provide the complete order code, serial number, process connection, transmitter version, output option, approval markings and a clear installation photograph.
Why should the configured gas data be backed up before changing 65F15-AE2AG1AA?
The measurement depends on the selected gas or mixture and reference conditions. Preserving the configuration prevents a mechanically correct replacement from reporting the wrong normalized flow.
What should be checked after reinstalling 65F15-AE2AG1AA?
Confirm flow direction, grounding, wiring, configured gas, units, reference conditions and a stable zero-flow reading before comparing the device with the process balance.
