Flow Meters & Metering Systems

The Advantages of Differential Pressure Meters

Each flow meter approach has its design limitations due to the complexities of liquids and gases flowing through elbows, pipes, pumps and other pipeline structures. Unlike orifice plates and other instruments, V-Cone meters provide extremely accurate and reliable measurements in pipe sizes up to 120 “with limited straight pipe length constraints and virtually no maintenance.

Similar to other flow measuring devices based on the Bernoulli Principle, which describes the relationship between a fluid’s velocity and a fluid’s pressure, the V-Cone model calculates the difference between the pipe’s full bore pressure and the post-constriction pressure. This offers almost instant response time to pressure changes across an extensive range of flow rates and flow characteristics. Since a V-Cone is its own flow conditioner, friction in the incoming stream does not interrupt it, regardless of the medium or how long the straight pipe leading to the meter.

The number of technology options for reliable metering of liquid, steam, or gas media is becoming more limited as pipeline sizes become larger. When evaluated against other metering technologies, V-Cone technology integrates an assortment of design features to deliver convenience of installation and maintenance in addition to accuracy reading for applications that are new or retrofitted.

V-Cone technology provides many advantages when used in pipelines, beyond accuracy and repeatability. It has a small footprint, the permanent pressure loss remains low, its reinforced design can handle surges, turndown range is excellent, and there is no recalibration necessary.

Three of the Most Commonly Used Water Metering Devices

The volume of water used by a residential or business facility supplied with public water is measured using a device known as a water meter. Water metering can also be used to determine the flow of water at a specific location in the system. Water meter readings are the responsibility of the water company, however … Continued
