Indicative Price : 20.00 USD

General Description:
Multi or single jet water meter, 13 mm (½ inch) bore diameter.

Technical Specifications:
Multi-jet or single-jet type water meter suitable for horizontal and/or vertical installations.
Nominal bore diameter 13 mm (½ inch).
Maximum working pressure 10 bars.
Testing pressure 20 bars.
Testing temperature 50ºC.
Maximum operating water temperature 40ºC.

The water meter employs statically and hydro-dynamically balanced rotor, offering the minimum possible interruption to flow.
Magnetic direct drive, extra dry, easy-to-read dials and register with an anti-fogging glass and leak detection star.
The register has a metallic (or plastic) housing with cover, and may be rotated through 360 degrees with a stop at the selected angle and must be approved according to E.E.C./ISO standards.
The body of the meter is metallic, made of a corrosion resistant material, coated with epoxy coating on the interior and the exterior faces.

The totaliser mechanism is on-site-interchangeable.
An internal adequate filter (strainer) is fixed on the inflow side.
The meter will be connected to the adjacent pipes through threaded connections in accordance with ISO R7 (BS 21).
Smallest readable unit 0.1 litres.
Maximum register reading 99 999 cubic meters.
Nominal flow rate Qn = 1.5 cubic meters / hour.
Maximum flow rate Qmax = 3 cubic meters / hour.
Minimum flow rate Qmin = 30 litres / hour.
Transitional flow rate Qt = 120 litres/hour.
Accuracy between maximum and transitional flow (+ 2%).
Accuracy between minimum and transitional flow (+ 5%).

Packaging and labelling:
Water meters are individually packed in strong carton boxes. The final packing in strong shipping boxes depends on the total number of meters shipped.

Comments:
The following definitions of terms used in the specification are according to ISO 4064.

Maximum flow rate (Q max): The highest flow rate at which the meter is required to operate in a satisfactory manner for a short period of time without deteriorating.

Nominal flow rate (Q n): Half the maximum flow rate (Q max).

Minimum flow rate (Q min): The lowest flow rate at which the meter is required to give the indications within the maximum permissible error tolerance. It is determined in terms of (Q n).

Transitional flow rate (Q t): The flow rate at which the maximum permissible error of the water meter changes in value.
