DECON Industries Limited is also dedicated in precise flow metering technologies, the main flow meter products include Rectangular Meters, Wedge Meters, Venturi Tubes, Nozzles and Orifice Flow Elements.
The Rectangular Flow Meter is actually a wedge type Venturi tubes or eccentric venturi, is a differential pressure producing device for use on all fluids especially slurries and fluids with suspended solids, the rectangular meter is particularly effective on fluids with low Reynolds.
1. Rectangular Meter features and applications
The rectangular meter use the partial or eccentric straight through conduit (Called RECTM Throttling Throat) to avoid solid articles (or power) accumulating before the throttling section in the pipe.
With clean and smooth through curved throttling face, make it suitable for abrasive fluids, with tungsten carbide coated smooth face, the anti-abrasive ability is strongly enhanced, and the working life of keeping accurate measuring can be as long as 5 to 10 years.
It is insensitive to pipe Reynolds Numbers which can be as low as 1000 for viscous fluid, 6500 for gas and light liquids.
As it combines the venturi tube properties, it can be used to measuring flow with stable high accuracy and linearity, as well as reliability.
2. Rectangular Meter features and applications
There are 2 kinds body pipes for wedge type venturi, Both rectangular pipe and circular pipe for this kind of flow meter can be available, rectangular pipe rating CL150# - 600#, circular pipe rating CL150#-2500#.

3. Integral Rectangular Mass Flow Meter
Integrated with Multi-Variable Transmitter to measure gas or steam mass flow accurately.
Rectangular Flow Meters.pdfThe DECON Venturi Tube is a differential-producing primary flow element that accurately and repeatable measures the flows of liquids or gases in closed and full pipe use conditions.
The venture tube incorporates an efficient hydraulic shape with static pressure taps in the throat and inlet sections, the venture tube can be manufactured according to ASME/ISO5167 Standard
Application
The cast iron series is often used in municipal water and waste water applications, fabricated venturi series can be used for high pressure or high temperature applications such as petrochemical and power industries.
Known for longevity of service with minimal maintenance, venturi tubes are ideal for metering water, sludge, slurries, gases, clean fluids, steam, chemic or petrochemical products.
Flow Measurement Accuracy
For pipe Reynolds numbers greater than 75 000 and with a normalized piping configuration, the DECON Venturi Tube provides a flow measurement accuracy of ± 0.50% without flow calibration.
With independent flow calibration, DECON provide the user with ± 0.25% accuracy.
Pressure Range/End Connections
Flanged end connections per ANSI B16.1 for 125 PSIG to 2500 PSIG service are available.
A variety of other end connections is also available including: Butt Weld, Socket Weld.
Reliability
The DECON Venturi Tube is free of protrusions and sharp-edged, debris-collecting annuli.
Static pressure taps reduce flow noise. The internal contour is designed to minimize the buildup of solids and deter erosion, corrosion, and scaling.
Energy Savings
DECON Venturi Tubes operate with minimal head loss. This results in less energy consumption, lower operational costs, and a lower cost of ownership.
