Welded Pad Type Indicator


Model No. : MI - 07
The "Mayur Instruments" make Welded Pad Type Indicator (Side Mounted). It is a reliable device for direct reading the level of liquid. It is a simplest form of level indicator. These Welded Pad Type Indicators find wide application for level measurement in process tanks, batching tanks / storage / overhead etc.

Welded pad offer you a direct view of the liquid through flush mounted toughened glass set ready to weld base pad. Toughened plate glass gaskets cover plate and bolts precision machined seat offers perfect sealing for 40 kg/cm2 pressure test. (Indian glass/imported glass).

The Welded Pad Type Level Indicators are used where conventional gauge and valve construction is impractical because of solid matter in suspension, under conditions where the thermal error caused by piping to a gauge glass cannot be tolerated or wher space requirements suggest their use. Included are applications involving high vibration, highly viscous liquids or liquids with considerable amounts of solids.

PRINCIPLE
The Welded Pad Type Level Indicator unit is designed to be welded directly onto a tank or other liquid containing vessel. Standard Liquid Level Gauge units are furnished with a flat bottom.Upon request the unit can be machined with a cylindrical radius to match the contour of the vessel. The Liquid Level Gauges are available in single or multiple types.
