Our Reflex Level Gauges are highly useful to provide excellent indications of the liquid level of colorless liquids, using a Prism glass. It produces high contrasting indications of levels of liquids, which can be viewed through the mirror like surface placed above. The distinct line of separation of liquids can be sighted from many meters away. Construction wise, it comes with a reflex glass which is clamped within the gauge body and seals the front opening of the liquid or vapor space.

Its application with steam:

• Up to 32 bar saturated steam

We provide excellent magnetic level indicator (gauge), which uses a float with built-in magnetic system that travels up and down in a measuring pipe connected to the tank(communicating pipe system). During this up-down motion, it transmits the liquid’s level inside the tank to an indicating scale, which provides clear visibility.
The indicating scale is fastened to the pipe in such a manner that there is no direct contact with the medium.

It’s Design:

• Comes with double casing type, so that it can be used for either heating or cooling jackets.

Advantages of using this gauge:

• No glasses or Mica sheets are used, hence no fear of cracks or break at high pressures.
• More safety features.
• Low maintenance.
• Relative ease of maintenance.
• Less leakage points than those with direct indication.

Our Side Mounted Level Switch has wide range of applications in controlling liquid level. The whole assembly comes with (side) flange mounting, and a provision of cooling fins can also be incorporated for high temperature applications. It uses a Micro switch assembly, along with brass counter weight and a powerful (Alnico) magnet. The change in level causes the float movement, The magnet mounted in the stem of the float creates a repulsive magnetic force, which further actuates the micro-switch.

Some of the features of this product are:

Cost effective.

Light weight.

Low maintenance and easy mounting.

Components & parts in the wet region or exposed areas are made of stainless steel.

Prevention of dry running of the pump during overflow, with the direct control facilitated by the switch.

Our Top Mounted Level Switch is highly regarded for its enduring applicability in continuous level measurement of liquids of high viscosity. It also can be used in high-pressure application areas, for liquids, which are corrosive and hazardous in nature.

It consists of a float which buoys-up, thus moving the connecting stem through magnetic link to a switch assembly mounted on top during the rise of liquid level inside the tank.

In our Strainers category, we provide two types of Strainers, namely : Y-Type strainers and Basket-Type strainers.

Y-Type Strainers:
