'Venturi' V Cone Flowmeters From McCrometer

The High-Accuracy, Fit-Anywhere Venturi Flowmeter

The V-Cone is an advanced differential pressure-type flowmeter, ideal for tight-fit and retrofit installations. Employed in today's most challenging applications, it offers users high accuracy and repeatability, extremely flexible installation and no maintenance. The installation flexibility of the V-Cone Venturi meter is due to its ability to condition the flow prior to measurement. It has been employed successfully in oil and natural gas production and distribution, process and facility control, and the municipal water/wastewater sector.

With no moving parts to replace or maintain, the V-Cone Venturi meter offers long term performance with low operating costs. In addition, the meter never needs recalibration, so once installed, it can operate unattended for years. All these benefits add up to a great flowmeter for your toughest and tightest applications, when high accuracy and repeatability are a must.

Key Features

• No straight pipe runs
• Pre-conditions flow
• Repeatability to 0.1%
• Accuracy to +/- 0.5%
• Low headloss
• Low maintenance
• No recalibration

How it Works

The V-Cone Venturi meter is a differential pressure type flowmeter with a unique design that conditions the flow prior to measurement.

• Differential pressure is created by a cone placed in the centre of the pipe.
• The cone is shaped so that it "flattens" the fluid velocity profile in the pipe, creating a more stable signal across wide flow downturns.
• Flow rate is calculated by measuring the difference between the pressure upstream of the cone at the meter wall and the pressure downstream of the cone through its centre.

Product Configuration

The V-Cone Venturi flowmeter is available in a wide variety of configurations to meet the requirements of ANSI, DIN and JIS standards. Use the following table to find the model, configuration and size best suited to your application.

Sizes larger than 24" are available on most models on request.

NOTE

• Each V-Cone is sized for the intended application. Specific performance ratings are obtained through the sizing process.
