Product Overview
Calibration is what turns a Cox turbine into a measurement you can certify. Every meter ships with a 10-point MIL-PRF-7024 wet calibration on a 1.12 cSt solvent standard, run on primary-standard calibrators at an NVLAP-accredited lab and traceable to NIST, with a unique K-factor in hand. When your service differs from that solvent reference, the calibration scales with it: up to five viscosities for a Universal Viscosity Curve, a custom fluid from under 0.85 cSt into the 301–1000 cSt range, more than 50 data points for a finer characterization, UVC points written to the certificate for programming a flow computer, and an RTD calibration where the meter carries an RTD pickoff. The baseline is included with a new meter; the extended options are specified with it.
Key Features & Benefits
- Included on every meter — a new Cox meter arrives with a 10-point MIL-PRF-7024 wet calibration and its own K-factor — no separate order needed for the baseline
- NVLAP-accredited, NIST-traceable — calibrators are primary standards at the Badger Meter Flow Dynamics lab (NVLAP Lab Code 200668-0), so the certificate stands up to audit and acceptance
- Tight calibrator uncertainty — ±0.05% of reading at ±0.02% repeatability anchors the meter’s published accuracy
- Multi-viscosity UVC — up to 5 viscosities build a Universal Viscosity Curve so the K-factor tracks the fluid as it warms or cools
- Custom-fluid calibration — calibrate in water, the solvent standard, or your own fluid from under 0.85 cSt to the 301–1000 cSt range
- More data points on request — step from the standard 10 points to more than 50 where the duty needs a tighter map of the meter curve
- Flow-computer-ready data — add UVC programming points to the certificate, and an RTD calibration on meters specified with an RTD pickoff
Specifications
- Standard calibration
- Every Cox meter ships with a single 10-point MIL-PRF-7024, Type II wet calibration and a unique K-factor, included with a new meter
- Standard calibration fluid
- A solvent blend at 1.12 cSt, 0.762 specific gravity, at 80°F (MIL-PRF-7024, Type II)
- Calibrator uncertainty
- ±0.05% of reading, with ±0.02% repeatability
- Accreditation & traceability
- Run on primary-standard calibrators at the Badger Meter Flow Dynamics NVLAP-accredited lab (Lab Code 200668-0, Racine, WI), traceable to NIST
- Multi-viscosity options
- From 1 viscosity (standard) up to 5 viscosities for a Universal Viscosity Curve
- Fluid-viscosity options
- Water or the 1.12 cSt standard, or a custom fluid viscosity from under 0.85 cSt up to the 301–1000 cSt range
- Data-point options
- From 10 points (standard) up to more than 50 points
- UVC / programming data
- UVC points for programming a flow computer can be added to the certificate data
- RTD calibration
- An RTD calibration can be added when the meter ships with an RTD pickoff and flow computer
- Scope
- These options are priced and performed with a new meter; recalibrate on the interval your quality system or custody-transfer standard requires
Common Applications
- Custody transfer and aerospace acceptance testing, where the certificate is the proof of accuracy
- Fluids that differ from the 1.12 cSt solvent standard — ordered as a multi-viscosity UVC or custom-fluid calibration
- Periodic recalibration on the interval your quality system requires
- Heavier or higher-viscosity service calibrated up into the 301–1000 cSt range
- Programming a flow computer from UVC certificate data, with RTD calibration where temperature compensation is used
To arrange MIL-PRF-7024 flow calibration:
Use the input form to tell us your fluid, its viscosity and temperature, and your accuracy or custody-transfer requirement, and we’ll build the right calibration for your Cox meter.
