Product Details

MEISTER is a professional manufacturer of flow measurement and control equipment in Germany. Its flow switches are mainly mechanical float/piston structures, which do not require a power supply (pure mechanical contacts), have strong resistance to electromagnetic interference, high voltage resistance, and can be customized with ATEX explosion-proof, high temperature, and food grade materials; Covering the entire scene of liquids (water, oil, coolant) and gases (compressed air), it is widely used in industrial fields such as machine tools, hydraulics, cooling, lubrication, and chemical engineering.

Naming Rules for MEISTER Flow Switch Models (RVO/U-XX/YY)

RVO/U: Series code (float type, visual, flow switch)

XX: Size/Connection Code (1/2/3/4, corresponding to G1/4 '~G1')

YY: Flow rate value (L/min, water medium, vertical installation)

Suffixes: - L (with display), - EX (explosion-proof), - SS (stainless steel), - H (high temperature), etc

Typical application scenarios of MEISTER flow switch

Machine tool cooling system: spindle/guide rail coolant flow monitoring and low flow alarm.

Hydraulic/lubrication system: gearbox, bearing lubrication circuit to prevent oil shortage and dry burning.

Water treatment/HVAC: cooling water circulation, filtration system flow protection.

Chemical/Pharmaceutical: Neutral liquid transportation, optional ATEX model for explosion-proof areas.

Key points for selecting MEISTER flow switch

Determine the type of medium (liquid/gas) and viscosity (high viscosity requires DKME piston type).

Select the corresponding model according to the flow range (such as RVO/U-4/5 for 0.5-5 L/min).

Confirm the pressure/temperature and connection size (G1/4 '~G1').

Choose visualization (required RVO/U), explosion-proof (- EX), stainless steel (- SS) as needed.
