Safe filter monitoring with differential pressure gauges

Filter monitoring is really a core task of differential pressure gauges ? the differential pressure increases as soon as the filter becomes clogged. The measuring instruments thus signal when the filter should be cleaned or replaced. The efficiency of such a solution can be illustrated by the example of WIKA pressure gauges of the DELTA-line series in water treatment.
With microswitch and operating display ? the WIKA model DPGS40 differential pressure gauge enables safe filter monitoring.
In the water industry, reverse osmosis is a widely used process to separate water from unwanted substances. The corresponding filtration systems use semi-permeable membranes.
For filter monitoring, a global solution provider for the treatment of drinking, industrial and wastewater uses WIKA model DPGS40 differential pressure gauges in its plants in Germany. The instrument measures the pressure on both sides of the membrane.
Timely intervention at the filter
As well as the on-site display of the differential pressure, the pressure gauge has an integrated microswitch. This sends a warning signal to the control centre whenever a defined limit value is reached. This enables the operator to set up for timely cleaning or replacement of the filter. Because of its mechanical measuring principle, the filter monitoring also functions reliably in the event of a power failure.
Continuous monitoring
Prompt intervention at the filter is necessary for two reasons. Firstly: It prevents possible contamination of the water. Secondly: The operator saves energy through continuous filter monitoring. The more fouled a filter is, the harder the pump must work for the desired media flow.
Integrated working pressure indication
The customer find the DELTA-line pressure gauge for filter monitoring for another reason ? due to the integrated working pressure indication. This information is essential to the plant manager since it allows him to draw conclusions about the respective pump performance. To acquire this information minus the two-in-one solution, he would otherwise have had to set up yet another measuring location.
Further measuring weksler pressure gauge ราคา with filter monitoring, the differential pressure gauges of the DELTA-line series are suitable for tasks in level and flow measurement. In different versions, they cover a wide range of applications. DPGx instruments are available with analogue signal output or more to two microswitches. All have ATEX approval. Gleam variant with SIL certification and DNV-GL approval for marine applications.
