The importance of TDS for water quality monitoring
3 min read
Total Dissolved Solids (TDS) is a critical water quality indicator. Learn why continuous TDS monitoring is essential for cafés, restaurants, and hotels — and how TDSBot automates it.
What Does TDS Actually Do to Your Water?
Total Dissolved Solids (TDS) is a simple number (mg/L or ppm) that shows how many salts and other dissolved solids are present in water.
For a café, restaurant, or hotel, TDS is much more than a technical figure — it is an indicator of the suitability of the water used for making coffee, beverages, and food, as well as for providing drinking water.
When Should a Change in TDS Concern You?
Continuous TDS monitoring provides knowledge about:
- Whether the source or supply network has changed.
- Whether the performance of your filtration system (e.g. reverse osmosis) is declining and filters or membranes need replacing.
Without continuous monitoring, a shift in TDS often only becomes visible when a customer complains about product quality — or when an espresso machine or boiler starts showing problems due to oxidation or corrosion.
The Problem TDSBot Solves
TDSBot is an IoT water quality monitoring system that connects to your filtration setup (RO and other systems) and tracks:
- The TDS of both the supply water and the purified water in real time.
- Temperature, total water volume, and flow rate.
- Filter condition, with predictive maintenance alerts.
Everything is accessible through a web dashboard and an Android/iOS app.
How TDSBot Helps in Practice
- In the café: The owner or barista can see in real time whether the espresso machine's water has a TDS in the optimal range (e.g. 75–150 mg/L) and when the reverse osmosis membrane needs inspection or replacement.
- In food service: Steam equipment, dishwashers, and food preparation all run consistently, while TDSBot alerts you to TDS changes that would affect flavour.
- In the hotel: The same system protects coffee machines and other appliances, reducing scale build-up, energy consumption, and unplanned breakdowns.
The Advantage of Proactive Intervention
Instead of reacting once the coffee tastes off or a boiler develops a fault, TDSBot:
- Shows trends in TDS and water flow.
- Sends alerts to your phone when a check is needed.
This way, equipment problems are prevented, product quality stays consistent, and the customer experience is not left at the mercy of random fluctuations in water quality.
If you want to know in real time what is happening to the water in your business — and receive early warnings before any change shows up in your coffee, food, or equipment — TDSBot helps you turn your water filtration system into a smart, monitored quality system.
