Kobold has on offer the KSK/KSM plastic flowmeter and monitor that works on the suspended float measuring principle, where the float glides up and down in a conical measuring tube. The units, constructed of polyamide or polysulphone material, easily handle a variety of corrosive media, as well as all neutral media. Their light weight makes them ideally suited for systems which cannot be statically loaded, for example, non-stationary technical systems. They find application in cooling circuits, water treatment and plant engineering. The standard measuring ranges of model KSK are 1,5 –11 … 100 – 1000 l/h water and 0,15 – 0,45 … 20 – 105 Nm³/h air. Model KSM’s ranges are 15 – 150 … 8000 – 60 000 l/h water, 0.8 – 5 … 300 – 2500 Nm³/h air.
The maximum temperature range depends on the design and options, and varies from 60 to 100°C. Maximum pressure for KSK is PN10, (PN16 for KSM). The percentage scale can be replaced by scales with other units on request. The scale length and direct readability of the float position guarantee an accurate identification of the reading and a visual inspection of the measured medium. By upgrading the instrument with a potential free reed contact, users can also have an economical flow monitor with bi-stable function in addition to the flowmeter function. The screw cap allows an easy installation in any system. Corresponding screw fittings are available on request.

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.
