Key parameters
Type
VPInstruments VPFlowScope In-line Thermabridge thermal mass flow meter for compressed air and technical gases
Measurands
Flow, pressure, temperature, and totalizer (three-in-one sensor)
Flow Ranges
0.5 in: 0.23-80 m3n/hr; 1 in: 0.91-250; 2 in: 3.55-1000 m3n/hr (SCFM equivalents per brochure)
Flow Accuracy
0.5% FSS under calibration conditions with air (with calibration report)
Pressure Sensor
0-16 bar gauge standard (35 bar / 500 psi on request); +/-1.5% FSS (0-60 C)
Gas Temperature
0 to 60 C (32 to 140 F)
Fits compressed-air and technical-gas metering where you need a VPFlowScope In-line Thermabridge meter measuring flow, pressure, and temperature with Modbus and 4–20 mA/pulse.
Key advantages
- Measurands — Flow, pressure, temperature, and totalizer (three-in-one)
- Sizes / ranges — 0.5 in: 0.23–80; 1 in: 0.91–250; 2 in: 3.55–1000 m³n/h class
- Flow accuracy — 0.5% FSS under calibration conditions with air (with calibration report)
- Pressure — 0–16 bar g standard (35 bar / 500 psi on request)
- Outputs — RS485 Modbus RTU, 4–20 mA, and pulse; optional display/logger
Typical applications
- Compressed air allocation and leakage programs on branch lines.
- Technical gases (N2, O2, He, Ar, CO2, mixes) in-line metering.
- Submetering with optional bi-directional Thermabridge.
Selection guide
- Line size — 0.5 / 1 / 2 in and matching flow range
- Display — D0 none; D10 display; D11 display + ~2M point logger
- Pressure option — 16 bar standard vs 35 bar request
- Gas — Air vs named technical gas for calibration
Common mistakes
- Using in-line VPFlowScope on wet/saturated air — prefer VPFlowScope DP for wet air.
- Ignoring inlet/outlet straight-run needs on small branches.
- Ordering D0 then expecting on-meter logging.
When to RFQ / what to tell us
- Pipe size, gas, flow/pressure span.
- Display/logger and bi-directional needs.
- Quantity and ship-to.
