The flowmeter of the series KMT, based on the measurement principle of thermal mass flow, is ideally suited for the measurement of flow of compressed air and gases in pipes with size from DN 15...DN 300. Measurement of for instance the usage of compressed air, nitrogen, CO² or other non-corrosive gases.
The KMT is setting new standards in terms of measurement accuarcy and reproducibility thanks to its application specific adjustment during production. This flow meter is adjusted under a pressure of 7 bar (abs) (DN15...DN50) or 9 bar (abs) (DN65...DN300). Adjusting the device specifically for its application has the advantage of keeping the actual flow speed in the pipeline low even with very large flow quantites. Thanks to more stable flow profile, this low flow speed facilitates a much better degree of reproducility and accuracy than it the device were adjusted conventionally under normal pressure, as flow speeds upt to 200 mn/s can often no longer be controlled under conventional adjustment pressures.
The core design of the flow meter is based on the hot film sensor element, which is produced using the most modern thin film technology and has already proven itself time and time again in the automotive industry. This flow sensor features excellent long-term stability, a fast response time and an extremely high degree of reliability.
Two outputs are available, for further processing of the measurement data. Depending on the application, these outputs can be configured as analogue (current or voltage), switch output or as pulse output for the measurement of the consumption.
The KMT has a integrated counter for consumption. The consumend amount is shown on the display and the saved value is not lost even after power outage. The availability of the consumption amount as a free configurable pulse output is another helpful feature.
