Flowmeter suitable for food and semi-solid applications
February 2005Flow Measurement & Control
Transport (Industry)
This flow captor is a flowmeter for food and industrial applications, and is suitable for the measurement of liquids, semi-solids and a wide range of corrosive media. The small compact unit needs no additional parts. Two versions are available: an in-line version with an integrated stainless steel pipe, and a side entry version that must be inserted into the main flow. The stainless steel pipe runs through the centre of the in-line flow captor, and is the actual sensor element. The flow captor works according to a calorimetric measuring principle (a small part of the pipe is electrically heated) and the heat flow, depending on the flow speed of the medium, is measured electronically. This provides a linear output signal proportional to the flow speed.
Features include: an in-line unit is available in four different pipe sizes, a large measuring range, which is fully adjustable, the side entry version mounts with a nut and 'O' ring, low maintenance, good long term stability, non-intrusive sensing, and therefore there is no interference in the flow profile.
Applications where these features are important are in the process control of food, as well as chemical industries: cooling systems, cooling water for large machineries, steel industry, pump protection, liquid and oil applications, hazardous areas of underground mining, paper and pulp industry, in-line for small pipe diameters.

Editor's Choice Flow Measurement & Control
There are many processes where it is undesirable for the load to suddenly change quickly, for example in the paper industry. Examples of level control have involved reasonably fast tuning. An example of a level loop tuned this way and responding to a step change in setpoint is given.
