•Mechanical Level gauge
The main element of the sight glass level indicator is the body. Incorporated into this body are the liquid channel (if necessary the heating channel) and the seating faces for the chambered seals and sight glasses. Onto the body are mounted, or are already integrated, the valve heads and process connections. Drain or vent are also possible. The glasses and/or mica discs as well as the seals are fitted, secured and sealed with the aid of U-bolts and covers or pressure frames. Glasses from borosilicate glass in accordance with DIN 7081 are used.
Magnetic Level Gauges are a safe, economical way to measure and control liquid levels in any application. They are suitable for high temperature and/or pressure, full vacuum, low-specific gravity liquids, and more. Magnetic gauges can be used with vessels of almost any size and shape and with any process fluid.
Reflex type Level Gauges are suitable for non-viscous liquids in high pressure applications. Mounting at the side of the tank
•Ultrasonic level Indicator
Ultrasonic Level Transmitters / Indicators are suitable for measuring the Level if fluid in the tank by non-contact method. The Transmitter works on Sound Waves and the output from the same (4 to 20 mA) is given to a Digital level Indicator.
•submersible hydrostatic level indicator
Because these are small and submersible are universally more suitable for all kinds of hydrostatic level measurements. It is the ideal product for environments such as in the food and beverage industries, water level measurement and all kind of standard industrial and processing applications.
•Radar type level transmitter
Radar Level transmitter are non-contact level measurement devices based on radar principle. These level transmitters are available in Corrosive Liquids, Slurries, Solids, Coal, dusty media, and liquids with foam, condensate, hot liquids, and Cements, Acids, and Silos application
It works on the principle of measuring liquid Level by Ultrasonic waves. Transmitter generates & launches a continuous band of powerful ultrasonic waves aimed towards the surface of liquid. These ultrasonic waves of certain wavelength hit the liquid surface and get reflected back towards the transmitter's receiver sensor. Reflected signals are received by trans-receiver of the sensor, which processes them to interpret the liquid Level on the basis of generation, reflection & time receiving of ultrasonic waves
allow continuous level measurement. They are suitable for conductive and nonconductive liquids and offer excellent precision and stability under aggressive mechanical and chemical conditions.
Electronic displacer level transmitter technology operates by detecting changes in buoyancy force caused by liquid level change. These forces act upon the spring supported displacer causing vertical motion of the core within a linear variable differential transformer. As the core position changes with liquid level, voltages are induced across the secondary windings of the LVDT. These signals are processed in the electronic circuitry and used to control the current in the current loop. The enclosing tube acts as a static isolation barrier between the LVDT and the process media.
The device works through measurement of the electrical resistance between a sensing electrode and a reference electrode. This simple design incorporates no moving parts and makes this device especially Suitable for difficult applications, such as monitoring the level of low density liquids, high viscosity liquids, or liquids containing large quantities of suspended particulates
A signal from the electronic circuit excites a crystal in the probe causing the fork to vibrate. If the fork is covered by material, the change in vibration is detected by the electronic circuitry which causes the relay to change state after a one second delay. When the fork is free from material pressure, full vibration resumes and the relay reverts to its normal condition.
Float Switches are horizontally mounted and fitted from the outside of the tank, so do not require access to the inside of the tank.
The range of the level meters includes rotary level indicators suitable for solids. They consist of a probes rotated by electric motor, which meet greater resistance as levels rises. The increased driving torque of rotation is measured by an electromechanical or electronic device which thus indicates level. The rotary level sensors do not require calibration and offer excellent reliability.
