Filter monitoring is a core task of differential pressure gauges ? the differential pressure increases as soon as the filter becomes clogged. The measuring instruments thus signal once the filter must be cleaned or replaced. The efficiency of such a solution can be illustrated by the exemplory case 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 really a widely used process to split up water from unwanted substances. The corresponding filter systems work with semi-permeable membranes.
For filter monitoring, an international solution provider for the treating 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 comes with 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 by making use of 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 just one more reason ? as a result of integrated working pressure indication. These details is essential to the plant manager since it allows him to draw conclusions concerning the respective pump performance. To obtain this information minus the two-in-one solution, he would otherwise have had to create yet another measuring location.
Further measuring requirements
In addition to 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. เพรสเชอร์เกจลม have ATEX approval. Gleam variant with SIL certification and DNV-GL approval for marine applications.
