MICRO MOTION RFT97121PNU FLOW TRANSMITTER W/ CMF025M313NU FLOW SENSOR PRE OWNED/ NORMAL WEAR/ UTESTED/ WE WERE TOLD THIS WAS PULLED FROM WORKING ENVIRONMENT BUT CANNOT TEST ANY FURTHER SO WE ARE SELLING AS IS/ ?? What This Device Is The RFT97121PNU is a remote flow transmitter made by Micro Motion (now part of Emerson). It is not a sensor itself ? it works together with a Coriolis flow sensor to form a complete mass flow measurement system. ? In simple terms: Sensor (in the pipe) ? measures flow/density Transmitter (your unit) ? processes and outputs the signal ? What It Measures When paired with a Coriolis sensor, it provides: Mass flow rate (e.g., lb/min, kg/h) Fluid density Temperature (in some configs) Derived values (volume flow, concentration) These systems are widely used because they measure mass directly, not inferred like DP transmitters. ? Key Technical Details From available specs: Output: 4?20 mA analog signal Frequency output (scaled to flow) HART communication Power: Typically 100?115 VAC (~14 W) Density range: Up to ~5.0 g/cc Designed for remote mounting (separate from sensor) ? Typical Applications You?ll find this exact transmitter in: Oil gas (custody transfer, batching) Chemical processing Food beverage (precise dosing) Pharmaceuticals Any system needing high-accuracy mass flow ? What ?RFT97121PNU? Means (Generalized) RFT9712 ? transmitter family (classic Micro Motion remote electronics) 1PNU ? configuration (power supply, outputs, approvals, enclosure type) The CMF025M313NU is a Coriolis mass flow sensor from Micro Motion (Emerson) ? part of the well-known ELITE series. Measures mass flow directly (not inferred) Also measures: Density Fluid temperature Requires a transmitter (like RFT, 1700/2700/5700 series) to operate ? How It Works (Simple Explanation) Fluid flows through vibrating tubes The Coriolis effect causes a measurable twist The sensor converts that into: Mass flow rate Density ? This is one of the most accurate flow measurement methods available ? Typical Characteristics (CMF025 Series) Line size: ~1/2 inch (compact process lines) Pressure rating: up to ~850 psi Temperature range: approx -240C to +204C (varies by config) Accuracy: typically 0.1% or better (Coriolis standard) Material: usually 316L stainless steel ?
