Operating instructions for SIKA turbine flow sensor type VTY25 MS - Turbine flow sensor with threaded connection
The SIKA VTY25 MS turbine flow sensor has been specially developed for drinking water and industrial applications. With a flow range of 1...90 l/min and a nominal diameter of DN 25, the VTY25 MS offers high measuring accuracy, low pressure loss and an extremely long service life thanks to the use of high-quality bearings. The sensor is ideal for use in HVAC systems (heating, ventilation, air conditioning) and in water treatment.
Areas of application:
The VTY series was specially developed for series use in drinking water applications and offers reliable and precise measurements. Typical areas of application are
- Measurement of drinking water discharge at taps
- Monitoring of water systems in HVAC and industrial applications
- Water treatment and dosing systems
Mode of operation:
The inflowing liquid medium is divided into several partial flows by a perforated disk, which hit the rotor evenly and set it in rotation. The rotational speed of the rotor is detected by a magnet-equipped rotor and a Hall effect sensor and converted into a frequency signal(square wave signal) proportional to the flow rate.
- Hall effect sensor: The sensor detects the rotational movement of the rotor and converts this into an electrical pulse signal that is proportional to the flow rate.
- High-quality bearings: The sapphire and carbide bearings ensure a long service life and minimize wear thanks to uniform flow.
Main features:
- Flow range: 1...90 l/min
- Nominal diameter: DN 25
- Material: Brass for HVAC and industrial applications
- Measuring principle: Turbine with Hall effect sensor for converting the rotor rotation into a frequency signal
- Frequency output: Frequency-proportional square wave signal
- Pressure shock resistance: The sensor is pressure shock resistant, which makes it ideal for industrial applications.
Advantages:
- Long service life and low wear: Thanks to the use of high-quality bearing materials such as sapphire and carbide, the sensor is particularly durable and low-maintenance.
- Fixed pulse rate: The sensor offers minimal series dispersion thanks to a fixed pulse rate, which makes it particularly reliable in large-volume applications.
- High measuring accuracy: The sensor is largely independent of the installation position thanks to the integrated flow straighteners, which ensure high measuring accuracy.
- Pressure shock resistance: The sensor is insensitive to pressure shocks, which increases its reliability in dynamic systems.
- Space-saving: The compact design enables easy installation in confined spaces and systems with limited space.
Materials:
- Housing: Brass for industrial and HVAC applications
- Bearings: High-quality materials such as sapphire and carbide, which ensure a long service life and minimal wear.
Technical data:
- Flow range: 1...90 l/min
- Nominal diameter: DN 25
- Measuring principle: Turbine with Hall effect sensor
- Frequency output: square wave signal, proportional to the flow rate
- Connection options: The sensor can be supplied with 80 mm single wires with Molex Mini-Fit® Jr. connector or with a 0.5 m or 1 m PVC cable.
Summary:
The SIKA VTY25 MS turbine flow sensor offers a precise, durable and robust solution for measuring the flow of drinking water and other liquids in HVAC and industrial applications. Thanks to its fixed pulse rate, high measuring accuracy and durable design, the VTY25 MS is particularly suitable for use in large-volume applications. Its pressure shock resistant design and the ability to install it in various positions make it a versatile and reliable choice for numerous applications.
