FLO-CAL© Instrument Data Acquisition and Control Systems
Flow Meter Signal Conditioning and Timing System:
- Flow meter standards and unit under test inputs compatible with turbine, quadrature encoder (TTL), modulated carrier, and analog signal flow meters.
- Total of 5 frequency input channels through a programmable FLO-CAL conditioning board 4 for flow standards (or 3 flow std. and 1 density std.), 1 for UUT.
- Input frequency range: 10 to 30,000 pulses per second.
- Input signal ranges: multiple standards, including 0 to 5 VDC, 0 to 10 VDC, 0 to 20 mA, and 4 to 20 mA.
- Time base frequency: 1MHz, using on-board clock.
- Temp. and pressure sensors are part of the FLO-CAL© clock.
Analog Input System For All Signals: (including temperature and pressure).
- 16-bit resolution for analog to digital conversion
- Uncertainty: ±0.01% of full scale
Digital Output System For Liquid Control Valves: Up to four AC valves, via Opto-isolated modules.
Fluid Flow Measurement
Maximum Flow Capacity of System: 200 GPM.
Flow Standards Configuration:
- Up to 4 calibrated flow measurement standards, or 3 density standards.
- Low/medium flow standards are piston rotary prover type, and range from 4 to 100,000 cc/min. (26.5 GPM), with fluid viscosity in the range of 0.8 to 3000 cps.
- High flow standards are positive displacement standards, from 25 to 200 GPM. Higher flow rate available, consult ATC.
- Selectable flow units of mass and volumetric measure: cc/min, liters/hr, GPM, cubic meters/hours, g/sec, kg/min, lb/min, kg/hr, lb/hr
Repeatability: 0.05% to a primary mass standard. Total uncertainty:±0.2% of reading, per ANSI-Z540-2.
Over Flow Range Condition:
- Each flow standard has a protective solenoid valve, which is controlled by the FLO-CAL© program.
- Should fluid that flows through the system exceed the maximum flow rate, all fluid control valves close and the operator will be prompted to take appropriate action.
Maximum Working Pressure: 150 PSIG. For higher pressure, consult ATC.
Liquid Media: Multiple liquid types are supported, typically oil and petroleum based fluids; consult ATC for other liquids.
- Full bridge strain gage pressure transducer with electrical output
