GKM H4000 Woltmann Cold Potable Water Meters

GKM Helix 4000
GKM Helix 4000 Woltmann Cold Water Meter is a Woltmann-type meter designed for measuring bulk forward and reverse flows of cold potable water for revenue billing in commercial or industrial applications and distribution system monitoring. Its inductive register enables improved output performance and security while its robust shroud and copper ensure long term clear and accurate readability. The GKM Helix 4000 Woltmann is also compatible with the Emeris PR7 inductive pulse transmitter for effective water resource monitoring and management.

Available in six sizes for flow rates between 0.504 m3/h and 787.5 m3/h, the GKM H4000 operates at temperatures up to 50°C and a maximum working pressure of 16 bar. Accuracy maintained in both forward and reverse flow and the product offers the benefits of inductive-based pulse communications technology. The meter complies with all relevant international quality standards such as OIML R49 and ISO 4064 specifications for forwarding flow installations in horizontal, vertical andinclined pipelines.

Robust construction

Like all Elster meters, the GKM H4000is manufactured from the highest qualitymaterials for maximum resistance towear and corrosion. Meter body and cover are epoxies powdercoated for protection in all environments. Thrust pads and stub spindles aremanufactured intungsten carbide and jeweled rotorbearings are used for maximum wear life. All wetted materials areUK WRAS approvedagainst health risk.

Flexible installation

Installation can be in horizontal, verticaland inclined pipelines. The GKM H4000also achieves good performance inabnormal installations.

Intelligent metering

Fully compatible with Elster’s Emerisrange of intelligent meter reading systems, GKM H4000 can provide even more vital management information to assist with effective distribution management, reduce water losses from leakage and improve customer service. Whencombined with the Emeritus TRC600 unit(pictured below), a range of intelligentfeatures including leakage alarms, data logging, and tariffs enables a complete metering system that addresses theef ficiency objectives for water providers.
