Electromagnetic Water Meters

Woltmann Turbine Helical Vane Meters

Woltmann meters comprises of a rotor with helical blades inserted axially in the flow, much like a ducted fan; they can be considered a type of turbine flow meter. They are commonly referred to as helix meters and are usually used to measure bulk flows.

Combination Water Meters

Combination water meters comprises of a bulk Woltmann insert and a low-flow Volumetric insert or meter, flow is diverted between them by a by-pass valve that is set at a predetermined flow rate. This allows the combination meter to have a very large measurement range.

WRAS Approved Product

Whole products such as valves, boilers & showers undergo mechanical and water quality testing. This type of approval demonstrates full compliance with the requirements of the regulations and bye-laws, provided the fitting is installed according to any conditions given with the approval.

Compliant Water Meter

Elster Water Metering (Kent Meters)

Elster Water Metering (formally Kent Meters and now part of Honeywell) are an industry leader in the manufacture of water meters, which includes high accuracy mechanical meters, fully electronic water meters and Smart metering solutions for residential, commercial and industrial sectors.

Volumetric Positive Displacement Meter

Based on the volumetric rotary piston measurement principle, these meters offer the very highest levels of reading accuracy, even at the lowest flow rate. Optimum accuracy is maintained whether the meter is installed horizontally, vertically or on an incline.

ISO5211 Pad Mount for Actuator Operation

The top flange and drilling to ISO5211 specifications offer the widest possible selection of actuation options, as well as direct mount of pneumatic actuators and accessories.

Fire Safe Approved to API 607 4th Edition

Valves have been qualified by testing to API standards 607, 4th Edition. The valve design incorporates a secondary metal seat in the body, providing the required shutoff should the primary seats be destroyed by fire.

3.1 & 3.2 Material Certification (on request)

Multi-Jet Warm Water Meter

Multi-jet meters use multiple ports surrounding an internal chamber to create multiple jets of water against an impeller, whose rotation speed depends on the velocity of water flow. For best accuracy, they should be installed horizontally.
