Elster H4000 is a Woltmann type cold water meter designed for measuring bulk flows of cold potable water for revenue billing in commercial or industrial applications and distribution system monitoring.

Elster H4000 Water Meter is a horizontal Woltmann type water meter designed for installation where occasional low and moderate to high sustained flows are demanded. Accuracy is maintained in both forward and reverse flow directions and there are various register/pulser options to suit the metering application.

The water meter is for use only with potable cold water up to 120 °F (50 °C) and working pressure up to 230 psi (16 bar). The water meter will perform with accuracy registration of 100% +/- 2% within normal flow. Both pressure loss and accuracy tests are made before shipment. No adjustment is needed before installation.

The Elster H4000 is available in a number of different sizes from 1 ½” through 12″ covering a wide range of flow rates for accurate measurement of potable cold water.

Effective Water Metering

Elster H4000 meter uses an inductive register to deliver enhanced communications performance and tamper-proof security, offering protection against fraud.

The H4000 meter can be integrated with the Elster Emeris PR7 inductive pulse transmitter and provides both low and high speed bi-directional pulse capabilities as standard. The PR7 is fully compatible with ancillary devices including data loggers and AMR systems.

When used In conjunction with Elster H4000’s optional integrated pressure port, this allows convenient logging of flow-rate and pressure for effective water resource management.

Calculating Pulse Weights for Elster H4000 when fitted with PR7 inductive pulser.

Elster H4000 Water Meter

Elster H4000 Water Meter Register – from the dial plate customer can identify type of pulser and Pulse Factor.

Pulse weight is calculated by multiplying the Register “Pulse Factor” (P) by the PR7 “K_Factor” (K).

Pulse Weight (Litres per Pulse) = P x K.

PR7 is an open collector pulse transmitter suitable for data logging, AMR and telemetry equipment for the Elster H4000 water meter.
