Flow instruments are devices used to measure the flow rate or quantity of fluids—such as liquids, gases, or steam—moving through a system. The flow rate is typically expressed in terms of volume per unit time (e.g., liters per second, gallons per minute) or mass per unit time (e.g., kilograms per second). Flow instruments play a critical role in industrial, commercial, and environmental applications, helping monitor processes, control fluid distribution, ensure safety, and improve system efficiency.

V-TECH offers water metering solutions based on proven technology of Electromagnetic and represents the next generation of smart metering. V-TECH delivers solutions in all shapes and sizes. From individual meters and remote reading systems to fully automated service solutions. The meter is true volume measuring meter. The measurement is independent of viscosity, Density, Dissolved/ Undissolved solids, pressure or temperature of the owing liquid as long as it maintains certain minimum conductivity. Various types of Liners & Electrodes are used as per application requirements. Empty pipe detection is also provided.

V-TECH Displacer Type Level Switch works on Force Balance Principle. Displacer is suspended bya spring. When liquid level rises and covers the displacer, it becomes lighter and the spring relaxes.

This causes a small upward movement of the rod assembly inside the casing which activates themagnetically operated micro switch.Magnetically linked float & switch design providers a glandless Connection & ensure a leak free design. Such switches can handle liquids with have specific gravity as lowas 0.5

DESIGN FEATURES :

• Mounting:Min. 50 NB to 300 NB.
• Ideal for Deep tank or Sump for low alarm.
• Pressure : Vacuum to 40Kg / cm2
• Two / Four displacers available for pump control.
• Suitable for high temperature
• Level Height upto 20 Mtr
