SANWA Horizontal Multi-Jet Water Meter 1/2" (GMK15-H R80)

The GMK Model Water Meters fall under the group of Inferential Meters and has complete dry-dial, direct magnetic-drive , straight line reading and multi jet principle. The water enters into the Meter through the inlet pipe and properly designed. Strainer, and affects its action upon the Vane Wheel. The particular advantage of this Meter is the Magnetic transmission directly from the vane wheel to the register hermetically sealed, the register is thus completely isolated from the water , and is incorporated in a dry dial and is provided with magnet protection ring

Important Advantages

• Sealed Register: The register, consisting of gears and number rollers, is completely sealed to prevent water or impurities from entering. This eliminates fogging on the dial and avoids friction in the number display mechanism.
  
• Anti-Magnetic Protection: Effectively prevents external magnetic interference, ensuring accurate and reliable readings.
  
• Lightweight Impeller: The impeller is made of lightweight material with a magnet at the shaft end, which drives the magnet in the register. Only the impeller moves in the measuring chamber, reducing wear and friction.
  
• Clear and Precise Reading: Number rollers are aligned in a straight line, making volume reading simple and accurate.
  
• High Sensitivity at Low Flow: With no friction-causing components, the meter ensures precise measurement even at low water flow.
  
• Pilot Star Indicator: Located at the center of the dial, it shows water flow activity and helps detect pipe leakage.
  
• Easy Maintenance: Both the register and impeller can be replaced at a low cost.
