DSV-3

Product catalog summary

Overview: The document provides technical specifications and details for KOBOLD Messring GmbH's float-type flowmeters and switches, specifically the DSV model, designed for measuring and monitoring liquid flow.

Specifications:

Measuring Range: 0.25 - 1.25 to 10 - 130 l/min for water.
Accuracy: ± 4% of full scale.
Maximum Pressure (pmax): 10 bar.
Maximum Temperature (tmax): 100°C.
Connection Types: G¼ to G1¼ female, ¼ to 1¼" NPT female.
Materials: Brass or stainless steel.

Electrical Connections:

Connector DIN EN 175301-803.
Switching values for N/O and changeover contacts with various voltage and current ratings.

ATEX Compliance: The devices are suitable for use in explosive atmospheres, adhering to standards like EN 1127-1 and EN 60079-14, with specific zone and group classifications for gas and dust hazards.

Design and Functionality: The DSV model uses a cylindrical flow tube with conical slots, reducing dirt sensitivity. A permanent magnet in the float actuates an external reed contact, ensuring hermetic separation from the medium.

Applications: Suitable for machine tools, glass-melting tanks, cooling circuits, welding machines, induction furnaces, pumps, and low water level prevention.

Technical Details:

Housing: Anodised aluminium (non-media-contacted).
Connections: Brass or stainless steel, depending on the model.
Seals: NBR or FPM, depending on the model.
Installation Position: Vertical, with flow in the upward direction.

Device Versions and Dimensions: The document lists various models (DSV-1, DSV-2, DSV-3) with specific dimensions, thread types, and weights.

Order Details: Provides model numbers and configurations for ordering, including options for contacts and connection types.
