Delta Engineering

Aerofoil have application for air flow measurement through ducts. These are used where sufficient upstream and down-stream straight lengths of the duct is not available.

Aerofoil is compact and easy to install and maintenance free. It is fabricated and fitted in the duct of any shape square or rectangular .

ISA 1932 Flow Nozzles are used when low permanent pressure loss is desired and high operating pressure and high operating temperatures are involved. These are precision machined as per various International Standards.

ISA 1932 flow nozzles are generally mounted between flanges like an orifice plate and has corner pressure taps. The assemblies are available with Weld-neck,Slip-on and Socket - weld type flange mounting

Intake Cone has application for measurement of airflow of Compressors and Exhausters FD fans etc. These are manuf-actured precisely as per various international standards. When sufficient upstream and downstream lengths are not available Intake cone can be used efficiently in such application.

Intake Cone is fabricated, to suit the fan inlet. They can be des-igned for square, rectangular or of any shaped inlet of the FD fan or Compressor. They can have end flanges for mounting or can directly be butt welded to the pipe duct.

Integral Orifice Plate assemblies are the most useful for pipe sizes 40 NB and below. With these the Differential Pressure Transmitter is directly mounted on the Orifice assembly. This eliminates the impulse piping and the flow metering system becomes very compact.

Integral Orifice plate assembly can be provided with up-stream and downstream meter runs with end flanges as per the process requirement. This facilitates faster installation and becomes easy for cleaning maintenance.

Long Radius Flow Nozzles are used when low permanent pressure loss is desired and high operating pressure and high operating temperatures are involved. These are pre-cision machines as pervarious international standards.

Long radius flow nozzles are generally butt welded in the pipe and has D and D 2 pressure taps.These nozzles can also be AEROFOILmounted between flanges likean orifice plate.

Orifice plate assemblies are the most commonly used differential type flow measurement elements in the Process Industry for Flow Measurement application. These are precision machined as per various international standards. The assemblies are available with Weld-neck, Slip-on, Socket-weld and Screwed type flange mountings.
These are the simplest for installation and maintenance.

Venturi tubes are particularly used where permanent pressure loss is to be kept at minimum and high operating pressure and high operating temperatures are involved. These are manufactured precisely as per various International Standards.

Venturi tubes can be fabricated, machined or cast. They can be designed for square, rectangular or of any shaped duct. They can have end flanges for mounting or can directly be butt welded to the pipe duct.
