SI-3207 Small Turbine Flow Meter

The SI-3207 small turbine flow meter is specifically designed for measuring small-diameter pipes and low flow rates. It can be used to measure both instantaneous and total flow rates of liquids. Available in sizes from DN2 to DN10. Flow rates range from 30L/h to 160L/h. Customization options include a displayless design, a Hirschmann electrical interface, and a smaller footprint. Three-wire pulse output, two-wire 4-20mA output, or three-wire voltage output are available.

Applications

Liquid turbine flow meters are widely used in various fields due to their high accuracy and reliability:

1. Petrochemical Industry: Used for measuring various oils and chemical liquids, such as crude oil, gasoline, diesel, and chemical solvents.
2. Food and Beverage Industry: Used in food and beverage production to measure the flow rate of liquids such as syrups, milk, and juices.
3. Water Treatment: Used to control water flow in tap water and sewage treatment processes to ensure the rational use of water resources.
4. Pharmaceutical Industry: Used for flow monitoring in pharmaceutical production processes to ensure liquid flow control during production.

Case Study: Semiconductor Ultrapure Water Measurement

We supplied a customer with a requirement to measure ultrapure water with a conductivity of <0.055μS/cm to avoid metal ion contamination. We supplied them with a small-diameter turbine flow meter, using a PEEK turbine and sapphire bearings, and non-contact capacitive sensing technology. This achieves stable measurement with a reading accuracy of ±0.5%. This results in annual savings of 120,000 tons of water used for wafer rinsing.

Techincal Support

Sanitary Flow Meter

Sanitary Flow Meter, also called the tri-clamp flow meter. Sanitary Flow Meters have stainless steel bodies and come standard with Tri-Clover fittings.

Wastewater flow meter

Wastewater Flow meters are flowmeters for water and wastewater treatment. Electromagnetic flow meters are suitable for open channel and underground industrial water pipes. Magnetic flow meters can be Remote type, compact type, insertion type. And ultrasonic flow meters are another choice, if you can not change your pipes. Both ultrasonic flow meters and magmeters are inline flow meters.
