In addition to its highly accurate readings, the V-Cone is designed to cope with a number of challenges experienced in municipal and industrial water and wastewater measurement applications: Some people who hear “differential-pressure meter” associate it with other, more limiting DP meter designs — such as those relying on orifice plates, which can induce more turbulence and permanent pressure loss. The VM V-Cone System acts as its own flow conditioner, fully conditioning and mixing the flow prior to measurement. For clean water applications (left), the V-Cone meter measures the pressure differential between the pipeline before the cone and the interior of the hollow cone with an open port on its downstream side. For dirty water applications, it is important to incorporate the correct V-Cone model and to mount it correctly to take advantage of its low-maintenance performance and operational accuracy. The difference in V-Cone performance can translate into significant savings in downtime and labor expense relative to removing and cleaning fouled mag meter sensors. All DP meters calculate the volume of flow relative to the pipeline pressure before and after a change in the cross-section of the flow, based on Bernoulli’s theorem for conservation of energy in a closed pipe (i.e., velocity and pressure vary inversely according to the rate of fluid flowing through the pipe). V-Cone meters exhibit low permanent pressure loss as compared to other types of meters — including orifice and nozzle DP meters. This forces the flow in the center of the pipe to flow around the cone. The V-Cone … In new piping configurations, those straight-run requirements can translate into significantly higher pipe expenses and greater space demands. Ultrasonic flowmeters. A big factor in V-Cone accuracy is in how it creates and measures differential pressure in a way that does not compromise other performance factors.

V-Cone flow meter geometry, however, is quite different from traditional Dp meters. By that evaluation, V-Cone meters often provide a more cost-effective solution across a variety of applications. There is a better alternative for differential pressure (DP) metering accuracy in problematic applications where other meter designs might compromise performance. Normally, the low-pressure reading is taken through the hollow body of the cone itself. This video comparison shows how a V-Cone meter also creates a smoother flow through a pipeline. The basic operation of Coriolis flow meters is based on the principles of motion mechanics. Because a V-Cone meter creates a smoother flow and operates at a lower differential pressure than other DP meters, it experiences low permanent pressure loss and reduces energy costs for pumping (Figure 1). Figures 3A and 3B. Yes, V-Cone meters use a differential pressure transmitter to measure and convert the differential pressure signal from the primary element to an electronic signal that can be interpreted by a flow monitor or process control system. Rangeabliity: typical 40:1 5. The V-Cone flow meter is similar to other differential pressure (Dp) meters in the equations of flow that it uses. A V-Cone meter’s simple mechanical design overcomes confined spacing, pipeline turbulence, and even noisy electrical environments that can hamper other meters. Other types of meters can require from 10 to 20 diameters of straight pipe between them and a valve, elbow, or other pipeline components to assure accurate readings. Figures 2A and 2B. What flow applications does the V-Cone perform well in? Ashcroft's product portfolio of mechanical and electronic measuring instruments meets the needs and requirements of the process and OEM industries. When a cross sectional area of a closed conduit (or pipe) is reduced by a diametric change or by the use of a differential producer element, the velocity of fluids passing through the conduit are increased across the boundary change area (continuity equation). A conical flow … There is a better alternative for differential pressure (DP) metering accuracy in problematic applications where other meter designs might compromise performance. The mass flow meter does not measure the volume per unit time (e.g., cubic meters per second) passing through the device; it measures the mass per unit time (e.g., kilograms per second) flowing through the device. Bickenhill and Marston Green, United Kingdom, Privacy Policy and Terms and Conditions of Use, In-Depth Master Class: TDR Sensor - Solutions For Tricky Level Measurement Applications. The V-Cone meter is in many … This allows the meter to read the differential pressure without risking a clog within the hollow cone itself.

HAWK is the world leader in level, positioning, asset monitoring and flow measurement solutions and has won several awards for their technologies such as Acoustic Wave, Fiber Optic Sensing and Radar. While they are designed primarily for clean water flow, they can tolerate modest amounts of sand, minerals, or minor biological solids entrained in the flow. A second environment is in raw water intakes or wastewater effluent with turbidity or entrained solids that can foul electromagnetic sensors. How is it different from other DP meters… It operates on the … Other types of DP meters, however — such as orifice plates, vortex meters, and Venturi meters — use a smaller opening, create more turbulence, and use a differential pressure that is at least twice as high as a V-Cone meter. To prevent potential clogging of the cone port in dirty water applications (right), the V-Cone meter uses a sealed cone and measures the pressure differential between the pipeline in advance of the cone and the pipeline just after the cone. That is why they generate a higher permanent pressure loss, put more stress on pumps, and require higher energy costs (Figure 2).
