Hedland H621-604 Flow Meter
1. Product Overview
Model: Hedland H621-604 (H600 series, mechanical flowmeter).
Type: Gear (positive displacement) flowmeter, suitable for medium and high viscosity liquid flow measurement.
Typical Applications:
Hydraulic systems, lubricating oil circulation monitoring
Fuel consumption measurement, chemical process fluid monitoring
Flow management of mobile equipment (such as construction machinery, agricultural machinery)
2. Key Features
Flow range: Need to verify the specific model (for example, H621-604 may represent 0.5~30 GPM or similar range, different suffixes correspond to different ranges).
Accuracy: ±0.5%~1% full scale (depending on fluid viscosity and working conditions).
Output method:
Mechanical counter (local display of cumulative flow).
Optional pulse signal (frequency output) or 4-20mA (need to confirm configuration).
Media compatibility:
Liquids: hydraulic oil, fuel, lubricating oil, solvents, etc. (compatible with a wide range of viscosities, up to 1000 cSt).
Not applicable: media containing solid particles or highly corrosive media (unless special material versions).
Working pressure: up to 5000 PSI (depending on the model, H600 series is known for high pressure).
Temperature range: -40°F to +300°F (-40°C to +150°C).
3. Mechanical and installation specifications
Interface size: common 1/2" NPT, 3/4" SAE or other flange connection (need to confirm the model suffix).
Material:
Housing: high-strength aluminum alloy or stainless steel (corrosion resistant).
Gear set: hardened steel or tungsten carbide (wear-resistant design).
Protection level: IP65 (dust-proof and splash-proof, suitable for industrial environments)
