We are one of the foremost manufacturers and suppliers of a comprehensive assortment of Level Transmitter. Our range is appreciated for higher degree of accuracy, precision & compact design, durability and longer service life.

This is more reliable techniques for continuous level indication and controlling of any liquid, since it is add on magnetic level indicator, has no direct contact with actual liquid. Hence there is no question of corrosion, Sp. Gravity, temp, pressure, for smooth operation, this sensor tube is magnetically actuated with movement of magnetic float / tip.
Construction & Working:The sensor tube is manufactured from non magnetic material to achieve undisturbed flux. it contains chain of reed switches & resisters. A magnetic float are tip tracks the level & activates reed chain. The change in resistance is in proportional to level & same is converted into 4-20 ma current by loop power transmitter and LCD unit indicates the reading.

A flame arrestors is a device fitted to the opening of an enclosure or to the connecting pipe works in a system of enclosure and which allows gases or vapors to flow under normal operating condition, but prevents the transmission of flame and stops flame in order to prevent a large fire or explosion.
It has no moving parts which comprises of passageways of apertures (Flame Cell Channels) that allows vapor or gases to flow freely through a fine woven wire screen arrestor.
The arrestor simultaneously dispenses and cools an approaching flame to a temperature below the vapor ignition point.

Types:
Inline Type:are fitted in piping systems to protect down stream equipments
End of Line:are fitted to the end of pipe line or exit to a vessel to prevent flames from entering.
