• Meter for measuring heavily fluctuating flow rates

• Replaceable measuring insert in one unit, suitable for calibration Comprising: measuring insert as main meter, switch-over valve, CALYGA measuring capsule as bypass meter
• Bypass line integrated in housing cover. No risk of sedimentation or corrosion
• HYDROMETER CALYGA measuring capsule as bypass meter and non-return valve easily replaced on site
• Ideal design of housing and housing cover prevents sedimentation, stagnant water and air pockets
• Use of standard components ensures simple repair and low cost of spare part stocks
• No measuring errors in the switch-over range
• Good long-term measuring accuracy
• Low weight
• Installation: horizontal, rising pipe, downpipe, 90° tilted
• In order to secure a safe switch-over the WPV needs a minimum ingoing pressure of 0.6 bar (6m Wg)

• Compact length (similar to Woltman meter WS)
• Nominal diameter DN 50-100 mm
• For cold water up to 30 °C (safe up to 50 °C)
• Operating pressure: up to 16 bar
• Flange for PN 16
• Calibration to EO 6 (calibration regulations)
• Complete head unit with counter and sensors can be rotated by 350° for easier reading
• Main meter with multifunctional counter (MFD)
• CALYGA measuring capsule as bypass meter Bypass meter mounted on right of main meter (as seen in direction of flow) G 1/2 flushing connection and bleed screw

• Special flange holes
• Integrated outputs for remote reading and flow rate measurement
• Other models as bypass meters
