SI flow meter: Key points
Understanding flow velocity and rate conversion
Converting flow velocity to volumetric flow rate in round pipes involves the formula V = v x A, where 'V' denotes volumetric flow rate, 'v' represents flow velocity, and 'A' is the cross-sectional area of the pipe. It's crucial to maintain consistency in units of measure to ensure accuracy. For practical application, we provide charts to simplify this conversion, aiding in the quick determination of flow velocity based on volumetric flow rate and pipe diameter.
Accuracy specifications
The SI flow meter's precision is particularly noted for water due to its single-point flow velocity measurement. Factors such as turbulence, insertion depth, and medium variation can affect accuracy, making it essential to understand the conditions under which these meters operate optimally.
Chemical concentration impact
Changes in the concentration of chemicals, like glycol, can significantly impact the SI meter's evaluation signal. The sensor's response to varying glycol concentrations highlights the importance of maintaining a consistent medium composition to ensure reliable and repeatable measurements.
Temperature compensation
The SI flow meters are equipped to adjust to gradual temperature changes, ensuring sustained accuracy. However, rapid temperature shifts can momentarily influence readings due to the thermal flow technology's nature. The built-in temperature compensation feature eventually stabilizes the measurements, but users should be aware of this temporary sensitivity.
