Like other differential pressure elements SDF sensors generate a pressure difference that is quadratically proportional to the flow velocity and proportional to the media density.
The medium density changes with absolute pressure and temperature although the absolute pressure changes have although no impact on density of a liquid fluid.
To measure volume or mass flow accurately under changing operating temperature accurately it is necessary to measure temperature.
A Pt100 offers an accurate and economic solution to measure fluid temperature. We will take care of the correct device selection and best installation variant for you. At very high temperatures a thermocouple will be used.
A temperature sensors offers practical advantage wherever
- a flow measurement with fluctuating temperature is required,
- high accuracy is necessary,
- the entire measurement system shall be robust and proven,
