Measure
The system measures the flow of the incoming water and of the drain that has run through the substrate.
Drain Monitoring System · DMS
Know every morning that your drain is in order.
The system automatically measures what goes into and out of your substrate, per irrigation cycle. You see it in the app and get an alarm when the drain is not what you want, wherever you are.
- Strawberries
- Raspberries
- Blueberries
- Redcurrants
Why
A daily average does not show when things go wrong.
Drain is often still measured by hand and turned into a daily average. But what if it is too wet in the morning and dry in the afternoon? You will not see that.
If there is already drain at the first watering of the day, the plants stayed too wet during the night. That is not good, and you only notice it if you keep an eye on the first cycle.
We measure per cycle. You see right away what is happening and can adjust immediately. That counts even more on hot summer days, when some growers give some crops water more than 15 times a day.

The system in strawberry cultivation
From measurement to alarm in three steps
Understand
Every irrigation cycle is recognised and the drain is calculated per cycle. You see how it develops during the day.
Act
Too little water going in, too little drain coming out, or drain that starts too late in the morning? Then you get an alarm.

The Drain Monitoring System in practice
Insight throughout the day
See per cycle how much water goes in and out
Clear graphs show the millilitres in and out per irrigation cycle, and how the drain develops over the day. Set an alarm for when the drain starts too late in the morning, or is already there at the first watering. That way you step in sooner.
See drain, EC in and out, VPD and the weather on one screen, for today, the past week or the whole season.
In the web portal you analyse drain, EC and pH over the whole season and compare irrigation sections.
Give each crop, station or location its own colour, so you can tell them apart at a glance.

Extension
Add temperature and humidity
With a temperature and humidity sensor you see not only your drain but also the VPD, the vapour pressure deficit. It tells you how hard your plant is transpiring, and helps you understand why it needs more or less water.
Recommended if you want to see not only what the drain does, but also why.

What growers say
“With the Drain Monitoring System we can see faster and more accurately what the drain percentage is. Even per irrigation cycle! More insight means that at some moments we give less water than we were used to. On top of that, I am always up to date now, wherever I am.”
Gerco van ZuilenHead of field operations, Berrybrothers
Frequently asked questions
What is drain % and why measure it?
Drain is the share of the water you give that comes back out of the substrate. It shows whether your plant gets enough water and whether your irrigation amounts match what the plant needs.
Which crops is it meant for?
For substrate cultivation of strawberries, raspberries, blueberries and redcurrants. Do you grow another crop in substrate? Get in touch and we will look at what is possible.
When do I get an alarm?
When too little water goes in, when there is too little or no drain, or when the drain starts too late in the morning. With the pH and EC sensors you can also set alarms on acidity and EC value.
Can I also measure pH and EC?
Yes. The DMS PHEC and DMS PHEC PRO variants measure pH and EC in the incoming and outgoing water. With PHEC PRO you also measure the volumetric water content (VWC), the EC and the temperature in the substrate itself.
Can I get my drain measurements into my irrigation computer?
That is possible through a link. Many irrigation computers only support their own measurements, so we help you find the best approach for your situation. Ask about the options.
What does it cost?
That depends on the number of taps, the variant and the sensors. That is why we always make a tailored quote after a short conversation.
