Dwyer HFPS-3-4 Flow Meter
It is a thermal mass flow meter designed for accurate measurement of gas flow and is suitable for a variety of industrial and application scenarios. The following is a description of its core products:
1. Product Overview
Type: Thermal diffusion flow sensor, directly measuring gas mass flow without temperature or pressure compensation.
Typical applications:
HVAC, compressed air systems, combustion control, pipeline gas monitoring, etc.
Applicable to clean, dry or corrosive gases (depending on the probe material).
2. Key features
Measurement range: Typically covers low to medium flow (e.g. 0.1~100 SCFM, depending on the model configuration).
Accuracy: ±1~2% full scale (typical value).
Output signal: 4-20mA analog signal or optional digital communication (such as Modbus).
Media temperature: -40°C to +85°C (or higher, depending on the model).
Pressure level: Typically supports ≤150 PSI (specific parameters need to be verified).
