Multi Jet Wet Dial Plastic Water Meter for Cold Water
This multi jet wet dial water meter is engineered for cold water metering in residential and light commercial applications. Its robust multi jet design handles hard, scaling, or particle-laden water with ease, thanks to a hermetically sealed roller register filled with a special liquid and equipped with a pressure compensation device. This sealed register never contacts the water flowing through the meter, ensuring clear and legible readings throughout the meter’s service life.
Key Features of The Multi Jet Wet Dial Plastic Water Meter
⚙️ Sealed Wet Dial Register
The roller register is housed in a sealed chamber filled with a specially formulated liquid and incorporates a pressure compensation device. This design keeps the dial completely isolated from the water stream, so the reading window never fogs, scales, or becomes obscured — readings remain crystal clear and easy to read for years.
🛡️ Durable Plastic Housing and Movement
Both the meter body and the internal movement are manufactured from wear-resistant, waterproof, anti-magnetic, and anti-scaling plastic materials. This construction eliminates the risk of corrosion, scale adhesion, and magnetic interference that can affect metal-bodied meters.
🔄 Mechanical Transmission Immunity
The mechanical drive system is completely unaffected by external magnetic fields or iron particles suspended in the water. Unlike dry-dial meters that rely on magnetic coupling, this design eliminates the risk of magnetic tampering and ensures consistent, tamper-resistant measurement.
💧 Best of Both Wet and Dry Dial Designs
This meter combines the advantages of wet-dial meters (no fogging, no condensation, stable long-term accuracy) with the advantages of dry-dial meters (sealed register, protected from water-borne contaminants), while overcoming the inherent structural weaknesses of both traditional designs.
🌊 Multi Jet Measuring Principle
Water enters the measuring chamber through multiple inlet ports, distributing the flow evenly around the impeller. This balanced multi-jet design reduces wear on moving parts, minimizes the impact of velocity profile disturbances, and maintains accuracy even under challenging flow conditions.
