Sanpo WSP-50 DN50 Wastewater Water Meter – Woltman Flow Meter for Industrial Water Applications
✅ Sanpo WSP-50 DN50 is a Woltman-type wastewater water meter specifically designed for measuring the flow of raw water, wastewater, industrial water, and other liquids containing suspended solids or impurities. Its robust turbine design ensures accurate measurement, low pressure loss, and reliable long-term performance in demanding industrial environments.
✅ The meter operates using the Woltman turbine principle. As the fluid flows through the meter body, the turbine rotates proportionally to the flow rate. The rotational movement is transferred to the register through a fully sealed magnetic transmission system, preventing water from entering the counter mechanism and ensuring long service life.
✅ The meter body is manufactured from epoxy-coated cast iron, providing excellent corrosion resistance and durability for outdoor and industrial installations. The dry-dial register is protected by a durable transparent cover, allowing easy reading under various operating conditions.
✅ The WSP-50 model features a DN50 (2-inch) nominal diameter with flanged connections, making installation simple and compatible with standard industrial piping systems used in water treatment plants, factories, municipal utilities, and wastewater facilities.
✅ Designed with a wide measuring range and low head loss, the meter delivers stable and accurate flow measurement even under varying flow conditions. It is suitable for monitoring water consumption, measuring influent and effluent flow in wastewater treatment systems, and supporting efficient water management.
✅ With dependable performance, rugged construction, and cost-effective operation, the Sanpo WSP-50 DN50 is widely used in wastewater treatment plants, industrial water systems, food processing facilities, chemical plants, paper mills, textile factories, and municipal infrastructure projects.
