Flow metering without disruption
F low meters that involve moving parts are prone to errors and require a lot of maintenance. The new SU Puresonic flow meter from ifm has no moving parts inside the measuring tube and hence oers many advantages. In applications where conventional flow meters are aected by components in the measuring pipe, the SU Puresonic is an ideal solution. A typical problem of flow meters that involve moving parts such as a paddle wheel, for example, is that the wheels can become porous and break (a risk that increases over the service life) or that a blockage occurs due to foreign bodies in the medium. What is more, components can be damaged during cleaning and cause the meters to malfunction. The SU Puresonic flow meter works with ultrasonic technology. The ultrasonic transmitter and receiver are placed on the outside of the wall in such a way that the reflection occurs on the opposite inner side of the pipe. This means that no interfering structures are necessary inside the measuring pipe, which is made entirely of stainless steel. Another advantage: the sensor does not require any seals and ensures permanent tightness. The SU Puresonic is equipped with an operating status LED that can signal dierent status messages: for example, a deterioration of the signal quality due to air bubbles, particles or deposits, a failure of the electronics or the presence of a short circuit. In addition to green and red, the LED can light up blue, according to Namur NE107, to indicate a change in the process. As the SU Puresonic flow meter consists of a stainless-steel pipe with no components built in or protruding into it, the customer’s choice is simple. A time-consuming selection of the
appropriate meter based on the wet parts, or the sealing materials depending on the process parameters, can be dispensed with. The new flow meter is available in two sizes with process connections of 1” and 2”; the measuring ranges of the two models are 1...240 l/min and 5...1 000 l/min
