Reliable Industrial Flow Monitoring

Designed for rugged performance, the Series TDS Flow Switch offers trustworthy flow detection across a wide range of liquids and gases. Its industrial grade construction and IP65-rated enclosure provide excellent resistance to harsh conditions, making it ideal for continuous monitoring and protection of pumps and process equipment in plants and manufacturing facilities.

Easy Installation and Adjustable Settings

Fitted with standard 1 BSP threaded connections and available in 6 mm or 12 mm probe diameters, setup is straightforward for most pipelines. Users can fine-tune the set point externally using the potentiometer, ensuring precise operation tailored to application needs. Additional accessories for wiring and mounting further simplify the installation process.

Clear Status Indication and Fast Response

LED indicators clearly display flow and no-flow conditions at a glance, facilitating quick status checks and minimizing downtime. Typical response times range from 1 to 10 seconds, helping maintain dependable operation and protect critical downstream equipment from flow interruptions.

FAQs of Series TDS Thermal Dispersion Flow Switch:

Q: How is the set point of the Series TDS Thermal Dispersion Flow Switch adjusted?

A: The set point can be easily adjusted using the external potentiometer located on the unit. This allows users to fine-tune flow detection to the specific requirements of their application without dismantling the device.

Q: What types of media can the Series TDS Flow Switch monitor?

A: This flow switch is suitable for measuring both liquids and gases, including water and air, with a scale range of 0.03 m/s to 3.0 m/s for water and 0.1 m/s to 30 m/s for air. The wetted parts are made of SS 316 and incorporate Viton or Teflon seals, ensuring compatibility with a wide variety of process media.

Q: When should the Series TDS Flow Switch be used for pump protection?

A: Install the flow switch in systems where pump protection is criticalsuch as those requiring immediate shutdown in no-flow conditions. Its rapid response and accurate flow detection help prevent dry running and potential pump damage.

Q: Where can the Series TDS Flow Switch be mounted?

A: It features a standard 1 BSP insertion mount and probe diameters of 6 mm or 12 mm, making it suitable for most industrial pipework and manifold setups. The compact design and multiple cable gland options allow flexible positioning in confined spaces.

Q: What are the benefits of the IP65 enclosure for the Series TDS Flow Switch?

A: The IP65 enclosure ensures robust protection against dust and water ingress, ideal for operations in humid, dusty, or washdown environments. This level of protection extends the switchs operational life and reliability in industrial settings.

Q: How does the Series TDS Flow Switch provide status indication?

A: LED indicators on the device clearly show active flow or no-flow conditions, allowing operators and maintenance personnel to quickly assess system status and respond appropriately.

Q: What accessories are included with the Series TDS Flow Switch?

A: Each unit comes with wiring cables and mounting accessories, streamlining installation and setup. The epoxy powder coating also offers added durability for long service life.
