McCrometer Resource
McCrometer’s V-Cone® Flow Meter is an advanced differential pressure instrument which is ideal for use with liquid, steam, or gas media in rugged conditions; especially where accuracy, low maintenance, and cost are important.
In addition, as the V-Cone has very little upstream and downstream piping requirements, they are useful in tight-fit and retrofit installations where other meters may not work. In fact, most instances the use of V-Cones associated with chillers for chilled water in large institutional users are a matter of space, accuracy, and turndown.
With many large universities and other facilities such as hospitals and airports across the U.S., the reason for initial interest and subsequent purchases of V-Cones to measure Chilled Water was to fit within the confines of the existing and new buildings that were being used to house the chillers.

V-Cones have recently been selected for Steam service for mostly the same reasons as they are selected for Chilled Water. Space limitations in new and/or older buildings are a serious concern. V-Cones have the smallest piping requirements of practically any flow meter and continue to deliver accurate measurement, so they are fiscally responsible and cost effective. Additionally, in steam, they allow condensate and/or other small particulate matter to pass without affecting the measurement, thus giving much better accuracy instantaneously and over time.
Additionally, the delivered accuracy was important. In the past, most usage had been ignored, but with the rising costs associated with cooling, each individual building must be accountable for individual use. This is just good fiscal responsibility and management from an energy balance standpoint. Turndown was an issue because of seasonal swings in usage based on climate and population in the buildings at any particular time. Therefore, the meters needed to be able to have a large flow span (turndown), which remained accurate during continuous use.
