Although it looks different, the FPI Mag is still an electromagnetic flow meter and operates under the same principles of Faraday’s Law of Electromagnetic Induction. This states that when a conductor moves through a magnetic field, it produces a voltage and that magnetic field of the voltage is directly proportional to the velocity.
With proper maintenance, McCrometer meters have been installed in-field for decades. As a standard, we offer 2 -5 year warranties, and offer extended warranties at the time of purchase.
We do! The most common sizes are from 4” to 36”. Larger than this in diameter, we’ll need to review with McCrometer’s manufacturing and engineering teams. Feel free to reach out to McCrometer for more information.
For the best performance, McCrometer recommends grounding for all mag meters. Grounding reduces electrical noise that may affect the signal sent to your meter, which may affect flow data accuracy. We recommend grounding for all size of FPI Mags.
Testing THE NEXT GENERATION MAG METER
The FPI Mag is ideal for capital or maintenance projects, retrofits and sites never before metered. The unique combination of accuracy, ease of installation and total cost savings make the FPI Mag the perfect choice for a wide range of Municipal and Industrial Applications. It really is The Next Generation Mag Meter.
Yes! We offer solar power as an option, with battery backup.
Standard, McCrometer sizes meters for 10:1 turndown. We can go much lower than that, such as 30:1 or 50:1. It depends upon the conditions of the flow applications. The type of electronics configurations must be taken into consideration as well. For example, if you have a flow with a maximum DP of 250", a 250" transmitter would usually accompany that meter. However, if the meter is meant to measure down to almost 0" of water column, you might observe that the lower 50% of flow is in the bottom 10% of your transmitter's signal range. In order to compensate for that on high turndowns, you'll want to combine a 25" transmitter with that setup. Stacking your transmitters will give you the full range of accuracy in the signal measurement.
The V-Cone has a number of different approvals. The biggest one is for our European customers, the CE marker associated with the European Pressure Equipment Directive. Additionally, for Canadian approvals, we have the CRN, or the Canadian Registration Number. The V-Cone has approval for those in all Canadian provinces, and for customer model numbers, can actually apply for those new registrations. At this time, the V-Cone does not have any drinking water certifications, including NSF-61. Please refer to the Ultra Mag and FPI Mag for NSF-61 approved flow meters.
Finally, all V-Cones are calibrated at our on-site, NIST-traceable flow lab to the NVLAP certification of ISO 17025 for maximum accuracy.
This highly robust and durable meter has a standard lifespan of 25+ year. However, in speaking with longtime customers, many have V-Cones that have accurately measured for even longer - and we have the impressive technical data to substantiate those claims!
If you're looking to specify a V-Cone for your application, you'll need to gather a few pieces of information before getting started. You'll need process properties such as pressure, temperature, flow rate, and the fluid properties of the fluid you want to measure. Second, you'll need properties of your line including the internal diameter of your line, pipe schedule, and flange class pressure rating. Once you've gathered all this information, you can utilize McCrometer's V-Cone Sizing Tool and input information and receive preliminary engineering calculations to see what the DP in your line might be and to make adjustments as necessary.
The V-Cone can measure a wide variety of flow media (liquids, gasses, oils, steam, wet gas, etc.) in a number of industries such as oil and gas, power generation, pulp and paper, mining and metals, HVAC systems, wastewater and more.
The V-Cone is a highly customizable product. Leveraging our engineering assets, we're able to take customer specifications and create a custom metering solution. We accept simple requests like custom lengths and bi-directional flow, as well as complex requests like higher levels of material specification such as Hastelloy cones and internally cladded Inconel layer on low-temperature carbon steel. McCrometer has the ability to customize the V-Cone to meet a variety of customer needs.
McCrometer offers two different types of DP technologies. The first is our standard spooled V-Cone and the second is our compact, flangeless form factor Wafer-Cone. There are a number of similarities aside from the technology: the straight-run requirements are 0:3 upstream and downstream. There are also a number of differences, including accuracy (up to ±0.5% for V-Cone and up to ±1% for Wafer-Cone). The range of beta ratios is also the same, from 0 to .45 and 0 to .85, however, the form factor of the Wafer-Cone provides something very interesting: it has a hot-swappable, interchangeable cone! Over time, as conditions in your line change, you can change out the cone without the need to replace the entire meter. For example, a customer that is measuring with a 2" Wafer-Cone on a wellhead application can place that cone during the initial time of purchase. Over time, the flow of gas through the line may decrease, decreasing the over DP. If the customer would like to avoid buying a second, they can either replace the cone or utilize 1" custom reducers to simulate that of the 2" Wafer-Cone, eliminating the need for any pipe alterations.
There are a number of cone meters on the market today, however, there is only one V-Cone. McCrometer is the original cone meter. Our V-Cone was invented and patented in 1985, and has since been an industry leader in DP measurement. We have over 75,000 V-Cones installed in six continents across the globe, and that number continues to grow year over year.
AMI, or advanced metering infrastructure, is a network of water meters and data system management that allow two-way communication between the meter and your utility. McCrometer's smart outputs allow a seamless connection into these systems so you can get the data you need without needing to go searching for it.
Telemetry allows users to receive data from your meter to a cell phone or laptop through satellite or cellular communication. This is ideal for remote locations or locations with multiple sites, saving you time and money as users don't need to physically be present to check their meter's data. It sends the flow data directly to you!
Traditional liners, such as rubber liners, are not permanently affixed to the meter. This opens up the risk of delamination, or separation from the meter, causing untold damage downstream of the metering point. Instead, McCrometer uses a fusion-bonded epoxy that creates a seamless barrier between the meter and the pipeline fluid eliminating risk of delamination and guaranteed for the life of the meter.
The converter batteries are guaranteed for a 5-year battery life but may last longer than the guaranteed 5-year period. McCrometer also offers a DIY battery-replacement kit to get you back up and running in minutes, no need to send your meter back into the factory!
McCrometer offers AWWA and ANSI flanges 150# and 300#. For our 2" and 3" meters, we offer a wafer-style meter with optional spooling.
Straight-run recommendations vary based on the type of mag: insertion vs. full bore, as well as what obstructions you may have in your line. For example, for the Dura Mag, the 2" and 3" wafer-style requires 3 diameters upstream and 1 diameter downstream. For 4" and larger the Dura Mag requires 2 diameters upstream and 1 diameter downstream. For the FPI Mag, requirements vary based on obstructions like valves (gate, butterfly, double elbow) and can range from zero straight-run required to 7 diameters or more. There is extensive information on straight-run requirements in each mag meter's IOM, and additional support is offered from McCrometer's sales and technical support teams.
Smart Output reduces costs, calls, travel, and labor while increasing the efficiency of your system.
When Smart Output is included, an additional output cable is pre-installed to connect with your AMI transceiver.
McCrometer's mag solutions allow you to transmit data either on-demand or on a specific schedule, as well as receive diagnostic queries to keep the meter's operation current.
In cases where the interconnective devices aren't compatible or unique wiring is encountered, the connector may be removed, and a direct connection may be made.
