Liquid Level Indicator https://www.vautomatinstruments.com/liquid-level-indicator.htm https://www.vautomatinstruments.com/liquid-level-indicator.htm Liquid Level Measuring Instruments Sat, 07 Mar 2020 00:00:00 +0530 We offer our exclusive range of Liquid Level Indicators, The float cage is flanged to the tank & the level is indicated through a float, which consists of a Permanent magnet. Our Liquid Level Indicators are laterally to be flanged to the tank for communication of level of liquids and liquefied gases in open and closed tanks. These can be used when instruments with high resistance to pressure and temperature are required or if sight glasses or similar indicating parts for reasons of safety cannot be used. This measuring system is preferred because there is a safe pressure and gas tight separation between measuring and indicating parts. Magnetic level indicators can be either side mounted or top mounted Principle of Operation These models consist of Bi-coloured magnetic rollers equipped with small rod magnets which are rotated one after another at an angle of 180o by the directed field of the Permanent magnet inside the float. In addition, Level sensing elements can be fixed directly to the float cage, so that simultaneously liquid level is electrically measured through smart transmitter with output of 4-20mA. It is possible to connect Level indicating Meters and Set Point Relays at any distance for control and display purpose. The Magnetic Level transmitters can also be supplied with HART PROTOCOL. Moreover it is possible to attach bistable Magnetic Switches to the Magnetic Level indicator in order to get switching at any desired liquid level.

Displacement Liquid Level Transmitter https://www.vautomatinstruments.com/displacement-liquid-level-transmitter.htm https://www.vautomatinstruments.com/displacement-liquid-level-transmitter.htm Liquid Level Measuring Instruments Liquid Level Transmitters Sat, 07 Mar 2020 00:00:00 +0530 Automat displacement type Level Transmitter is designed to sense Liquid level, Interface and Specific Gravity. The output of the Instrument is proportional and is designed to measure and transmit electrical signal proportional to changes in Liquid level or Specific Gravity. Description The Displacement Liquid Level Transmitter changes in Liquid Level, Specific Gravity or Interface Level and transmits a current output signal proportional to the change in the process parameter. The change in the process parameter causes a change in the displacer position, which is transferred to the Torque Tube producing a rotary motion. This rotary motion is transferred through bellow to lever assembly that is supported by flexure strips. Magnets attached to the lever assembly move past a Hall effect position sensor that converts the magnetic field signal to an electrical 4- 20mAsignal. Brand Name V. Automat series 401ES Features Robust construction Highly efficient Durable High performance Low maintenance Guided Wave Radar Level Transmitter https://www.vautomatinstruments.com/guided-wave-radar-level-transmitter.htm https://www.vautomatinstruments.com/guided-wave-radar-level-transmitter.htm Liquid Level Measuring Instruments Liquid Level Transmitters Sat, 07 Mar 2020 00:00:00 +0530 Guided Wave Radar Level Transmitter can be used for measuring level or interface with 4-20mA standard current signal output. The measuring accuracy is not affected by change of specific gravity and dielectric constant of medium (in the setting range). It features itself easy operation and simple maintenance. The calibration at field only needs entering process data into the instrument. So, VAGWT is a new kind of level (interface) measuring instrument Guided Wave Radar Level Transmitter is designed for complicate and hard working conditions, the radar signal travels along the guided wave rod, instead it propagates in air, so measuring accuracy output is stable. The measuring performance cannot be affected by condensate on the rod. Lowest dielectric constant of the medium can be 1.4 (Example: butane). Measuring data have nothing to do with changes of working conditions (process temperature, process pressure & specific gravity of medium). VAGWT can trace the liquid level quickly.

Differential Pressure Transmitter https://www.vautomatinstruments.com/differential-pressure-transmitter.htm https://www.vautomatinstruments.com/differential-pressure-transmitter.htm Sat, 07 Mar 2020 00:00:00 +0530 V. Automat & Instruments (P) Ltd is one of the prime Manufacturers, Exporters and Suppliers of Differential Pressure Transmitter of 501 Series in India. 501 Series Automat Differential Pressure Transmitter is the part of series 501, consisting of certified electronic. 501 series SMART DP/PT are microprocessor-based instruments that combine the analog signal advantages (4-20 mA) together with the flexibility of digital communication using HART® protcol/Foundation Field Bus (FF). The DP/DT can be configured by using universal Hand Held HART communicator (HHT) or by Computer (PC) with dedicated Automat Software. Description : The medium pressure is transferred to the measuring chaff in the center of the chamber. The medium pressure is transferred to the measuring chaff which is elastic element used to check and measure the pressure acted on it. The displacement of the measuring chaffs [Max. 0.004 inch (0.10m)] is in direct proportion to the differential pressure. The position of the measuring chaff is detected by the fixed capacitive plates at two sides by means of direct digital capacitive circuit. The electronic signal is ambient, temperature compensated and amplified by the differential amplifier. The signal pass filter dampens the effects of process turbulence and prevents saturation of the DC amplifier and the current driver. The DC amplifier provides non interacting Zero and Span adjustments. Differential Pressure Transmitter adopt the principle of replacing analog signal amplifying circuit and A/D conversion circuit with direct digital capacitive circuit, and meantime take the digital compensation technology to compensate temperature and static pressure, which greatly improves the measurement precision and reduces the temperature drift. The complete unit transmitter is characterized by its small size, high reliability and long-term stability. With extremely high performance this microprocessor based digital smart transmitter is maintenance free & accurate. The circuit within the transmitter provides Reverse polarity protection, transient power surge protection, and Electromagnetic interference protection. Apart form flow measurement; DP transmitter can also be used to measure level and pressure.
