STM - Water Meter

Applications & Use Cases

• Monitoring water usage in food production lines for process control and efficiency.
• Measuring water flow for ingredient mixing and recipe adherence in beverage and food manufacturing.
• Tracking water consumption in cleaning-in-place (CIP) and sanitation systems.
• Ensuring compliance with environmental regulations by monitoring effluent water volumes.
• Optimising utility costs by identifying areas of high water consumption within a facility.

Typical Specifications

Typical flow rate range

For this class of equipment, flow rates typically range from 0.5 m³/h to 50 m³/h, depending on the pipe diameter and application.

Common connection sizes

Units of this type commonly feature threaded or flanged connections, typically ranging from DN15 (1/2") to DN100 (4").

Measurement principle

Water meters commonly operate on volumetric, turbine, electromagnetic, or ultrasonic principles, each suited to different flow characteristics and fluid types.

Typical accuracy

Accuracy for industrial water meters is commonly within ±1% to ±3% of the measured value.

Materials of construction

Components in contact with water are typically made from food-grade stainless steel (e.g., 304, 316), brass, or engineering plastics to ensure hygiene and corrosion resistance.

Power supply

Many industrial water meters are battery-powered for standalone operation, while others may require a 24V DC or 230V AC supply for advanced features or communication.

Output options

Common output options include pulse, 4-20mA, Modbus, or HART, allowing integration with PLCs and control systems.

Frequently Asked Questions

• What is the difference between a volumetric and a turbine water meter?

  Volumetric meters measure a fixed volume of water per cycle, offering high accuracy at low flow rates. Turbine meters measure flow by the rotation of an internal impeller, generally suitable for higher flow rates and less viscous fluids.

• Are these water meters suitable for hot water applications?

• How often do industrial water meters require calibration?

• Can this water meter be used for aggressive chemicals or highly viscous liquids?

• What installation considerations are important for a water meter?
