The easiste way to measure your flow rate per hour is to tank a bucket and a stop watch and measure how many litres flow in one minute. The measurment multiplied by 60 (mintues) will give you the flow per hour.

This device does the job for you without carrying and measuring containers.

Connection can be easly done with Gardena’s fast clip concept. As usual Gardena gives 3 years warranty.

The battery has to be replace every now and then.
