This water-meter is designed for potable or demineralized water as well as polluted water (by corrosion, scaling, particles, etc.)

• The water-meter Type 620 is a highly metrologic accurate meter.
• Designs of the measuring chamber and rotary piston allow even a drip counting.
• The Type 620 maintains its metrologic features throughout its lifetime.
• Readability is ensured with the plastic totalizer equipped with a wiper and with the glass-metal totalizer avoiding any condensation.
• The water-meter 620 easily fits into your pipings.
• Its anti-fraud design and robustness guarantee a long service life for the Type 620.

Accuracy and reliability:
With the design of the measuring chamber, the Type 620 has an extremely low start-up flow. It is supplied with a metrological lead compliant withMID 2014/32/EU regulations and a ratio Q3/Q1 of 400. The Type 620 is protected against solid materials present in the water by a tubing strainer and a filter. The finest particles can pass through the meter without damaging it: a patented system prevents particles from becoming trapped between the piston and the measuring chamber. The gears are located in the dry totalizer, which eliminates any risk of blocking by particles. The Type 620 water-meter maintains metrologic features throughout its lifetime, even under the most difficult conditions.

Readability:
The display on 8 reading rollers (5 for cubic metres and 3 for litres) and 1 pointer, guarantee a perfect readability. The resolution is 0.05 litres. The totalizer has a central disc allowing to visualize very low flow rates, thus, showing a possible downstream leak. The dial window is equipped with a wiper for optimum readability in all circumstances. The Type 620 can operate in any position, and its rotary dial can be rotated along 350°. This ensures easy reading regardless of the conditions of use. As an option, the water-meter can be supplied with a waterproof glass-to-metal totalizer (IP 68).

HRI pulse output option:
The totalizer is ready to assemble an HRI pulse output accessory. This device reproduces the mechanical index of the totalizer by detecting each rotation of the counter. It records both direction flows and therefore ensure an accurate measurement. It is an essential option for a remote reading and data transmission. Using the deciliter needle to activate the HRI provides a resolution of one or ten litres per pulse.
