Level Gauge
Vedika Instruments Pvt. Ltd. is a noted Level Gauge Manufacturers in Uttar Pradesh. Simplest design, offers accurate reading in water, chemicals, petroleum products and corrosive liquid Level measurement. Standard visible length is always less than C-C distance. The maximum operating pressure range is 10 kg/cm' and maximum operating temperature range is 300 ° C. Special featured valves with ball check arrangement. Isolation valves prevent the spillage of medium in the air. MS / SS-Tie rods/ or C-Channel protects the Glass Tube from any mechanical impact.
SS scale fitted adjacent to glass tube offers local reading effectively. Fix and relax design in level metering. Vent/Drain provision - Plug or Valve.

Rlg Series Glass Plated Liquid Level Gauge (Reflex Level Gauge) Top & Bottom Connection Orientation / Side-Side Mounted Type (Vipl-Rlg)
These gauges are used for measuring the level in a vessel. These can be used for maximum pressure of up to 150kg/cm' and a maximum temperature of 400' C. Constructional features include up to 2.5 metre single piece Construction with multiple glasses between process connections. A pair of auto shut off ball check valves in.
Working Principle
The principle of Reflex Level Gauges is based on the difference in the refractive principle of liquid and vapour. The liquid column is contained within the recess of the liquid chamber behind the sight glass which is clamped to the gauge body. The sight glass has prismatic right angled grooves on the side facing the liquid and vapor space. Light rays entering from outside the gauge are either absorbed or reflected depending upon whether they enter the liquid or vapour space. When the ray of light encounters the surface of one of the grooves in the vapor space, itis the opposite surface of the groove and from there, totally reflected back to the direction of observation. Thus vapour space appears as silvery white. When the light ray encounters the surface of the grooves in the liquid space, it is totally absorbed thereby the liquid behind the glass appear black.
Tlg Series Transparent Glass Type Liquid Level Gauge (Transparent Level Gauge) Top & Bottom Connection Orientation / Side-Side Mounted Type (Vipl-Tlg)
These gauges are used for measuring the level in a vessel. These can be used for maximum pressure of up to 150kg/cm' and a maximum temperature of 400’ C. Constructional features include 2.5 metre single piece construction with multiple glasses between process connections. A pair of auto shut off ball check valves in material of construction Carbon Steel or Stainless Steel and Polypropylene as optional.
Working Principle
Transparent Level Gauges employ two transparent glasses and a liquid chamber. The liquid level is indicated as a result of difference in the transparent properties of the two media. For water / steam applications, an illuminator is mounted on the rear side of the gauge with its light rays deflected upward into the water column. This enables the observer to see the illuminated surface of the water as the light rays impinge on the surface of separation between water and steam are reflected back to the eye of the observer. For High Temperature application mica shield is used.
