The flow-captor smart meter is the answer to the problems with insertion type flow meters. Flow rate through a pipe diameter will vary depending upon the nature of the flow profile (laminar or turbulent) and the insertion depth of the flow sensor. If the flow profile were known, then the flow rate at the insertion depth could be calculated and the flow rate accurately determined. In most instances, however, the flow profile is not known and measurement accuracy suffers. The flow-captor smart meter solves this problem by utilizing the 1/7 law. The variable insertion depth allows precise placement of the sensing tip at the optimum measuring depth for both laminar and turbulent flow.

Each flow-captor smart meter comes with easy to follow installation instructions and a detailed explanation of the 1/7 law, allowing you to quickly… get to the point.

Evolution of the flow-captor smart meter

Flow metering began with orifice blends, followed by magnetic inductive flow sensors, vortex shedding flowmeters, and other technologies. To utilize these principles of operation, the whole cross section of the pipe becomes the metering field. Thus, the sensor becomes, in effect, part of the pipe itself, mandating a different sensor for each pipe size. As a result these types of sensors are expensive to produce, difficult to install, and require excessive inventory. The solution to this problem was insertion flow sensors. They are much smaller, more cost effective, and easy to install. However, because they do not address the flow profile, due to their fixed insertion depth, accurate metering is nearly impossible to obtain. Despite this shortcoming they became very popular due to their simplicity and lower cost. Now the flow-captor smart meter using the 1/7th law has solved this accuracy problem.

However, the advantages don't stop here. What makes the flow-captor smart meter unique is the calorimetric principle developed by weber Sensors. This provides high accuracy measurement of flow (including very low flow rates) using a solid state design with no moving parts. The flow-captor smart meter sets the standard for flow metering.

Extreme accuracy at low flow rates

The application of the 1/7th law combined with the calorimetric principle technology, makes the flow-captor smart meter the flow sensor of choice for all industrial applications. It can measure flow of clean or dirty water, oil, glue, pastes, even wastewater and slurry. Because the smart meter does not contain any moving parts, such as paddlewheels or turbines, there is no risk of clogging or mechanical damage, the smart meter operates maintenance free. An optional hastelloy or titanium body construction is available for aggressive media.
