smart meter - the solution for big pipe flow metering The flow-captor smart meter is the answer to the problems with insertion type flow meters.
then the flow rate at the insertion depth could be calculated and the flow rate accurately determined.
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.
In most instances, however, the flow profile is not known and measurement accuracy suffers.
If the flow profile were known,
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
Extreme accuracy at low flow rates
Flow metering began with orifice blends, followed by magnetic inductive flow sensors, vortex shedding flowmeters, and other technologies.
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.
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.
● Accurate flow metering even at very low flow rates ● Linearized analog output for inter-facing with recorders, ratemeters, PLC's
Now the flow-captor smart meter using the 1/7th law has solved this accuracy problem.
● Easy insertion depth adjustment for pipes from 1.5" to 24" diameter ● Solid State design. No maintenance as there are no moving parts to stick or wear out
However, the advantages don't stop here.
The flow-captor smart meter sets the standard for flow metering.
The 1/7th diameter insertion law, applicable with the flow-captor smart meter, ensures high measurement accuracy under almost all conditions.
Key features:
Despite this shortcoming they became very popular due to their simplicity and lower cost.
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.
Turbulent flow is a very common flow condition characterized by a flat flow profile across the pipe diameter starting almost immediately after the pipe wall. Applying the 1/7th law creates the same accurate metering as under laminar flow conditions.
● Ideal for handling aggressive and hard to measure media ● Compact, rugged industrial design ● Minimal inventory requirements one smart meter fits all pipe sizes up to 24”

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.
It can measure flow of clean or dirty water, oil, glue, pastes, even wastewater and slurry.
Laminar flow is the ideal flow condition with no obstruction or bends. Under this condition the flow rate at an insertion depth of 1/7th of the pipe diameter represents the average flow speed across the pipe diameter.

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.

Principle of operation The flow-captor smart meter’s operation is based on an advanced calorimetric technology. The sensor head of the flowcaptor contains two PT-resistors. One of them is measuring the temperature of the media, while the other is heated by an attached heating resistor, resulting in a temperature difference between the two PT-resistors.

The temperature difference between the two PT-resistors is predetermined and a control circuit keeps this temperature difference constant. The flow of the media cools the heated PT-resistor proportional to the speed of the flow. The heating power fed into the system by the control circuit, in order to keep the temperature difference between the two PT-resistors constant, is the equivalent to the heat dissipation by the flow of the media. This results in a linear output signal proportional to the flow speed.
