Product catalog summary

Application
The WESAN WPV A 226/216 is a bulk water meter designed for measuring heavily fluctuating flow rates. It is suitable for horizontal installation and features a bypass meter that can be positioned on either side. The meter ensures no measuring errors in the switch-over range and maintains good long-term accuracy. A minimum ingoing pressure of 0.6 bar is required for safe operation.

General Specifications
The meter operates within a medium temperature range of 0 to 30°C and can withstand temperatures up to 50°C. It functions effectively in ambient temperatures up to 55°C and is approved under national standards 6.152 / 82.05. The device is classified under metrological class B and has a protection class of IP 68.

Technical Data
The meter is available in nominal diameters ranging from 50 to 200 mm, with corresponding nominal flow rates from 15 to 250 m³/h. It can handle a maximum short-term flow rate of up to 650 m³/h. The transition flow rate and minimum flow rate vary by diameter, ensuring precise measurement across different flow conditions.

Pulse Outputs
The meter includes pulse outputs for remote reading, with reed switch and IR pulse transmitter options. The pulse output varies by nominal diameter, providing flexibility in data collection and monitoring.

Display Range
The main meter display range varies by diameter, with options for both smaller and larger volume measurements. The bypass meter supports a display range of 0.05 l to 99,999 m³ across all diameters.

Dimensions
The meter's dimensions, including overall length, flange diameter, and height, vary by nominal diameter. The weight of the complete meter ranges from 17.4 kg to 159 kg, depending on the size.

Special Versions
Special versions are available upon request, including different nominal pressures, special flange holes, and integrated pulse outputs. Electronic counter modules can be added to both the main and bypass meters.

Graphs
The document includes pressure loss and typical error graphs, illustrating the meter's performance characteristics under various conditions.
