Fileder Filter Systems
Filter health read remotely, from the pressure drop
At a glance
Client: Fileder Filter Systems, one of the UK’s largest process-filtration suppliers
Site: Customer sediment filters
Instrumented: Filter inlet and outlet
Kit: iLink with two water-pressure sensors (ΔP) and a flow sensor
Period: 2022 pilot
The challenge
Checking a distributed fleet of customer filters meant sending technicians to read pressure gauges by hand.
What we installed
- iLink — One per filter
- Water pressure × 2 — Replace the inlet and outlet gauges
- Flow & Temperature — Flow, to compute filter resistance
Alarms that did the work
- Consumable pressure drop exceeded · Critical — pressure_drop · threshold set per process
- Consumable flow capacity reached · Critical — max_flow_quantity_reached · litres since last reset
What the data showed
Clogging made visible
In an obstruction test the pressure drop grew from about −0.1 to −0.26 bar.
One threshold per process
The operator sets the alarm level for each filtration process.
Resistance beats raw ΔP
Dividing ΔP by flow gives a health metric that holds when flow varies.
Results
- Filter monitoring: Remote, continuous — Replaces manual gauge readings
- Filter replacement: Usage-based — Triggered by ΔP and litres treated
“Using the Droople Water Intelligence Solution allows us to fully monitor our filter fleet remotely … we know exactly when every filter must be exchanged, avoiding any downtime.”
