Safe filter monitoring with differential pressure gauges

Filter monitoring is a core task of differential pressure gauges ? the differential pressure increases when the filter becomes clogged. The measuring instruments thus signal when the filter needs to be cleaned or replaced. The efficiency of this type of solution could 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 separate water from unwanted substances. The corresponding filter systems use semi-permeable membranes.
For filter monitoring, a global 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
In addition to the on-site display of the differential pressure, the pressure gauge has an integrated microswitch. This sends a warning signal to the control centre when a defined limit value is reached. This enables the operator to set up for timely cleaning or replacement of the filter. Due to 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 essential for just two reasons. Firstly: It prevents possible contamination of the water. Secondly: The operator saves energy with the aid of continuous filter monitoring. The more fouled a filter is, the harder the pump has to work for the required media flow.
Integrated working pressure indication
The customer find the DELTA-line pressure gauge for filter monitoring for just one more reason ? as Tragedy of integrated working pressure indication. These details is important to the plant manager because it allows him to draw conclusions about the respective pump performance. To obtain this information minus the two-in-one solution, he’d otherwise have had to set up yet another measuring location.
Further measuring requirements
Besides filter monitoring, the differential pressure gauges of the DELTA-line series are ideal for tasks in level and flow measurement. In various versions, they cover a variety 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.
