WESAN WP HE CHECK 725

Product catalog summary

Application
The WESAN WP H E CHECK 725 is a fully electronic hydrant tester designed to measure the actual water flow in cubic meters per hour (m³/h) for cold water up to 30°C. It provides highly accurate billing data recording.

Features

Includes a hydrant meter, pressure gauge, carrying/protective handle, and fixed B-coupling input/output.
Electronic counter module with IP 68 protection, mechanical switch for display change, and M-Bus interface compliant with EN 1434-3.
Equipped with a lithium battery with a 10-year lifespan and an optical ZVEI interface.
Rotatable integrator and a single-line 7-digit display for easy reading.
Pulse output of 100 liters per pulse for both forward and return flow.

Pulse Outputs
The outputs are open-collector circuits requiring external current limiting with a collector resistance of 1 kΩ at 30 V. They must operate in floating mode if the M-Bus is connected.

BULK WATER METER | HYDRANT TESTER PULSE OUTPUTS The outputs are open-collector circuits. The collector branch contains only 0 O resistance, i.e. there is no internal current limiting. If required, this must be provided externally by a collector resistance of 1 k£2 (at 30 V). The pulse outputs must be operated in floating mode if the M-Bus is connected.
