Pulse turbine cold water meter | Baylan Dn-200 Woltmann W5

Baylan Woltmann W5 DN200 pulse-output turbine cold-water meter

💧 The Baylan Woltmann W5 DN200 is an industrial mechanical meter designed to measure high volumes of cold water in 200 mm pipelines.

It is suitable for industrial plants, municipal networks, pumping stations, irrigation systems and other installations with high water consumption.

🏭 High-flow applications

• industrial facilities;
• municipal water networks;
• pumping stations;
• water-intake facilities;
• irrigation networks;
• greenhouse facilities;
• commercial metering for legal entities;
• internal industrial sub-metering.

⚙️ Woltmann turbine principle

Water flow rotates a turbine positioned along the pipe axis. Its rotation is transferred to the mechanical totaliser.

The meter must operate in a completely filled pipe with a stable water flow.

📏 DN200 size

• nominal diameter — DN200;
• nominal bore — 200 mm;
• connection type — flanged;
• common installation length — approximately 350 mm;
• gross weight — 81.2 kg.

📊 Flow rate

The local supplier lists a nominal flow of Qn 350 m³/h. Other catalogues list Qn 400 m³/h for a Baylan W5 DN200 version.

The exact value must be taken from the passport supplied with the individual meter.

❄️ Cold water

The common version is intended for cold water from +5 to +50 °C.

🛡️ Working pressure

Maximum working pressure is 1.6 MPa, or 16 bar.

📡 Pulse output

The meter includes a pulse output for connection to external data-acquisition equipment.

It can be connected to:

• a data-acquisition controller;
• a pulse logger;
• a GSM/GPRS modem;
• a monitoring system;
• an automated water-metering system.

A pulse output is not an integrated GSM modem.

Remote transmission requires an external modem, power supply, SIM card, server and system configuration.

🔢 Pulse value

The volume represented by one pulse must be verified from the passport or pulse-sensor marking.

Do not configure the receiving system using an assumed pulse value.

🔩 Flanged installation

• the mating flanges must be correctly aligned;
• new flange gaskets must be used;
• bolts must be tightened gradually in a cross pattern;
• pipe weight must not be transferred to the meter;
• required straight pipe sections must be provided.

💦 IP68 protection

Schetchik.uz lists IP68 protection. The permitted immersion depth and duration must be confirmed from the supplied documentation.
