HAM FilterSense
The HAM FilterSense monitors the condition of a water filter. It measures the conductivity, temperature and flow of the water, and calculates total dissolved solids (TDS).
The serial number starts with e52:.
What it measures
Section titled “What it measures”| Reading | Unit | Note |
|---|---|---|
| Electrical Conductivity | μS | Electrical conductivity of the water |
| Total Dissolved Solids | ppm | TDS. Calculated from the conductivity (TDS Factor setting) |
| Temperature | °C | Water temperature |
| Liquid | L | Total quantity that went through |
| Liquid flow rate | L/min | Current flow |
Settings
Section titled “Settings”The settings are on the device page, in the Settings section. For the general procedure see Device settings.
- TDS Factor: the conversion factor from conductivity to TDS, from 100 to 2000. The default is 500. Usual values: 500 for sodium chloride water, 640 for mixed water, 700 for water with much carbonate.
- Pulses per Litre (in Advanced): how many pulses the flow meter sends for each litre. Set the value of your meter.
- NTC Type (in Advanced): the type of the temperature sensor, 10kΩ (B3950) or 50kΩ (B3950). Keep the value that HAM set.
- Calibration table (in Advanced): field correction for temperature and conductivity. Tap Calibrate to fill it in.
- Device Description: text that shows as a subheading in reports.
- Include in summary views: the device shows in the summary views on the home page.
- Allow LAN commands (in Advanced): other devices on your local network can control this device. Keep the setting off if you do not need it.
- Force IPv4 (in Advanced): the device uses only IPv4 connections.
- Do not keep track of data (in Advanced): the app keeps no reading history.
Recommended rules
Section titled “Recommended rules”The app has no ready-made rules for this device. Create an alert when Electrical Conductivity goes above a limit and an alert when the device goes offline. See Create a rule and Offline alerts.
