WaterFlowKit

The WaterFlowKit offers a complete solution for monitoring your water consumption. You can connect up to two water flow sensors per kit. Each sensor can also optionally measure water temperature (depending on the selected version).

The WaterFlowKit is ideal for applications such as monitoring water consumption in a kitchen faucet , shower, or toilet . It's also ideal for use with a heat pump : with G1 pipes (flow and return), you can connect two sensors to measure both the flow and temperature of the pipes. This provides insight into the heat output and consumption of your heating circuit.

Every water flow sensor you order from us comes with a special 1-meter cable with connectors on both ends. Without this cable, it's not possible to connect the sensor to the WaterFlowKit.

What's in the box?

• WaterFlowKit: The core of your water monitoring, providing real-time insight into water consumption and temperature (if selected).

• Water flow sensors (order separately): Up to two sensors can be connected per kit. You can choose from the following sizes and models:

  • G1/2" – DN15 – approx. 15 mm pipe – YF-B1 (without temp) or YF-B7 (with temp) – suitable for standard household pipes
  • G3/4" – DN20 – approx. 20 mm pipe – YF-B5 (without temp) or YF-B6 (with temp) – often used for boilers and garden irrigation
  • G1" – DN25 – approx. 25 mm pipe – YF-B10 (without temp) – ideal for main water pipes and heat pumps
  • G1 1/2" – DN40 – approx. 40 mm pipe – YF-DN40-S (without temp) – for larger pipes, e.g. swimming pool systems and industrial applications
  • G2" – DN50 – approx. 50 mm pipe – YF-DN50-S (without temp) – for very large pipes, high flow and industrial installations

  Please note: the mm measurement is an indication only; this may vary due to the wall thickness of the tube.

  Our sensors are available in Brass and Stainless Steel :
  • Brass: robust and economical, suitable for most household applications.
  • Stainless Steel: Food safe, hygienic and recommended for drinking water or when extra durability is required.

• Optional: USB-C Adapter Set (3 meter cable)
  • EU version: suitable for standard EU sockets.
  • Universal version: with interchangeable plugs for use in the US, UK and AU.
• Manual: For a quick start and easy installation of your WaterFlowKit.

Frequently asked question about use in heating circuits

A common application is measuring the flow and temperature in a heating circuit (for example, with a heat pump or underfloor heating). Our DN15 and DN20 sensors reliably measure between 1–25 L/min (DN15) and 1–30 L/min (DN20). This is sufficiently accurate for most heating circuits, even at lower flow rates. By placing two sensors on the supply and return, you can visualize both the flow and the temperature difference. This allows you to calculate the power output (heat output) and the daily consumption of the circuit.

Which sensor should you choose?

Choose the sensor based on the diameter of your pipe (G size / DN size / mm indication) and whether you also want to measure temperature. For example, with a standard 15mm pipe, use the G1/2" (DN15) sensor, and if you also want to measure temperature, choose the YF-B7 model.
