Virtual Instrumentation & Software Applications Private Limited

We are a prominent manufacturer and supplier of Electro Magnetic Flow meter that consists of a sensor and a transmitter. Our range finds extensive application in chemical industry, power generation and distribution, mine, water treatment, paper industry, pharmaceutical industry, food and environmental protection. As per Faraday Law, the flow meter is used to measure volumetric flow rate for inductive liquids and pulps. Available in various output signals, the measurement in the flow meter is independent of the viscosity, density, temperature, pressure and conductivity of the measured fluid. The flow meter is ideal for the measurement of pulp due to absence of moving parts in the tubes. This kind of design leads to no loss of pressure and minimizes the requirement for the upstream and downstream straight pipes.

We are engaged in fabrication of Ultrasonic Level Transmitter that is used to take measurements of the level of liquids, where physical contact with liquid is not possible. The transmitter is designed with a “blind zone” of 0.25m close to the sensor, where at this point measuring capability of instrument lapses.

During the use of the equipment following points must be noted:

• Avoid spurious echoes which are not reflected by the surface
• Take care of the positioning of the METER sensor
• No obstacles should interfere with the ultrasonic wave emission lobe

We fabricate this range of Ultrasonic Level Transmitter in the following specifications:

• Housing material: PBT/PP wetted part
• Mechanical installation: 2”GAS M on request PP flange DN80
• Protection degree: IP65
• Electrical connection: Internal push actuators connectors

• Power consumption: 2-wire max 0,6W / 4-wire max 1,5W
• Relays output: (4-wire only) -n°2 3A 230Vac
• Digital communication: 4-wire: RS485 / HART (optional)
• Max measure range : Standard max 0.25÷5m (In case of non perfectly reflecting surfaces, the maximum distance value will be reduced)

V-Cone Flow Meter is an advanced differential pressure type Instruments. Employed in today's most challenging applications in oil / gas production, chemical, food & beverage , plastics, pharmaceuticals, textile, power and water & wastewater applications. V-Cone is especially useful in tight-fit and retrofit installations in which the long runs of straight pipe required by Orifice Plates, Venturi Tubes, and other technologies are either impractical or unavailable.

With no moving parts to replace or maintain, the V-Cone offers long term performance with low operating costs. In addition, the meter never needs recalibration, so once installed, it can operate unattended for years.

The installation flexibility of the V-Cone is due to its ability to condition the flow prior to measurement.
