WI / WI-NKP — turbine meters for irrigation water and treated effluent DN40–250, up to 16 bar
Country: Poland · Model: WI / WI-NKP
WI is a turbine water meter for DN40–250 for metering irrigation water from rivers and reservoirs and discharge of treated effluent in pressure pipelines. It operates at temperatures up to 50 °C (classes T30 and T50) and pressure from 0.3 to 16 bar (PN16). Main users are land reclamation systems, agricultural enterprises, water utilities and treatment plants.

Description
Installation is permitted in horizontal pipelines with the register facing up, as well as in vertical and inclined ones. The measuring insert can be removed without dismantling the body and is the same for all diameters, which simplifies maintenance and the range of spare parts. The vane runs on double-sided bearings, and the register is locked against turning beyond 358°. The body is painted cast iron, with flanges per PN-EN 1092-2 (PN10), DIN 2532, DIN 2501 or BS 4504. The -03 version has a six-drum sealed IP65 register with plastic covers, -NKP is prepared for an NK reed sensor, and -08 has an IP68 register for inductive modules. The meter is designed for AMR remote reading systems.
How to choose
The diameter is chosen by flow rate. The size range is DN40, 50, 65, 80, 100, 125, 150, 200 and 250. Per PN-EN 14268, the nominal flow rate Q3 is from 20 m³/h for DN40 to 630 m³/h for DN250, the maximum Q4 is from 25 to 787.5 m³/h, and the minimum Q1 is from 1 to 31.5 m³/h. According to the manufacturer's own data, Q3 reaches 25–700 m³/h and Q4 50–1 400 m³/h. The error is ±5 %, the register capacity is 9 999 999 m³, and the scale division is 0.005 m³. Length is from 200 mm (DN40–65) to 450 mm (DN250), and weight from 7.8 to 43 kg.

FAQ
What water is the WI meter intended for?
For irrigation water from rivers and reservoirs and for treated effluent from treatment plants in closed pressure pipelines.
Can the insert be serviced without dismantling the body?
Yes, the measuring insert is removed without taking the body out of the line and is the same for all diameters.
How do the -03 and -08 versions differ?
The -03 version has an IP65 register, and -08 has an IP68 register for inductive communication modules. The -NKP variant is prepared for an NK reed sensor.
What hygiene approvals does the meter have?
The product has PZH hygiene approvals and a declaration of conformity.
