Cox - Precision Gas Flow Turbine Meters
From Mechanical Flow Meters - Cox
Cox Precision Gas Flow Meters are designed for precise and repeatable flow measurement of all compressible fluids, with the added benefit of minimal pressure loss. To accommodate the requirements of most gaseous flow applications, Cox Precision Gas Meters come in a variety of sizes, end fittings and options. The gas models feature three basic rotor designs to compensate for low, medium and high density gases.

Features:
- Comprehensive pickoff selection
- High-performance ceramic ball bearings
- Three rotor designs
- NVLAP* (Lab Code 200668-0) accredited facility with NIST traceable standards
Benefits:
- Meets application requirements for temperature and electronic outputs.
- Provides near-perfect roundness, higher Rockwell hardness and are lighter and more tolerant to temperature than 440C stainless steel bearings. They eliminate adhesive wear and perform well in non-lubricating fluids.
- Rotor blade angle is matched to the density of the gas to optimize the flow range.
- Third part audits to ensure calibration uncertainty. Laboratory correlation to verify that all calibrators produce the same result.
Performance Specifications:
- Repeatability: 0.25% (of reading)
- Calibrator Uncertainty: ± 0.20% (of reading)
- Frequency Output: 1500…1800 Hz (Maximum)
- Pressure Rating: 5000 psi (4 times less than burst)
- Response Time: 20…30 milliseconds, or better
