Patented method

The patented fuse for the pipe

Leakage, burst pipe, forgetfulness, vandalism

All are characterized by a non-stop water flow!

However, even with many water withdrawals at the same time, at some point a short break is measurable.

That is exactly what is being evaluated!
Automatic time limit of a water flow

Patented process

  • The water supply is always closed and will only be opened if necessary!

  • Regardless of the pipe diameter and without mechanical sensors, even the smallest flow rates are detected and displayed.
  • If water flows nonstop and longer than the preset time, it will automatically shut off.
  • The shut-off valve is monitored and kept in operation by the constant movement.
  • An innovative hardware and software reduces the circuits and the average power consumption to less than 6 watts.

Questions and Answers

What else is different and why?

Why no limits for maximum flow or flow / time (pipe breakage, filter breakage, etc.)?

These limit values are actually unknown, since, for example, in the case of a pipe burst, the location and also the type are decisive for these limit values. But - leakage begins almost always creeping, in the drop area by pitting, misprints, material fatigue such as cracks in filters, etc., which then increase rapidly or very slowly in size.

This is measured and therefore warned at the beginning or shut-off before a large damage can occur.

Why not use Cloud, FlowTimer + App etc.?

The FlowTimer+ is not a smart metering product, but a standalone security system. As reliable as a fuse in the electrical distribution. Everything that acts unnecessarily from the outside could disturb this basic function.

Why alarm via SMS?

The most reliable way is to send an SMS from device to device. Cloud, messenger or other services are sometimes unsafe, not reliable or to slow.

Why an external smartphone?

Almost everyone can use a smartphone without any problems, and the alarm forwarding programs are used from millions of users. Both are therefore mature, very reliable and inexpensive.

How can I irrigate the garden for hours, for example?

Buy a wireless switch socket with feedback or a socket timer. This can be used to deactivate the protective function during irrigation.

What do I do if I want to tap water for more than 30 minutes without a break?

The maximum non-stop flow time can be easy set in 6 steps from 20 minutes to 120 minutes by pressing a button.

How does the system react to the smallest leaks?

Micro-leaks are displayed, with small leaks it is also shut-off. This alarm / shut-off threshold can be adapted to the respective application in 6 stages if required.

Why not wireless connections within the system?

To connect multiple Flowtimer +, FlowTimer + Protect devices or a smartphone, etc., only cables are used. This is the most interference-proof connection and otherwise usually complicated configuration is not necessary. The external pre-alarm can have a radio connection, since it is only for comfort and not safety.

What about Smart Home?

There are cable adapters available that can be connected to almost all popular smart home systems. Only the functions "trigger alarm" or "receive alarm" are available.

What must be considered during installation?

There must be upstream of each FlowTimer + a backflow preventer or KFR valve installed in the flow direction. Normally, this valve must already be installed behind the water meter. However, if multiple FlowTimer + are used (such as fuses), each requires such a valve.

The installation position of the shut-off valve is arbitrary, it only has to be installed in the correct direction (observe flow direction arrow on the valve). In the flow direction behind the valve, the pressure sensor must be installed. This can usually be screwed in directly instead of existing 1/4 inch bleed valves or be installed in the pipeline by means of a tee with a reduced outlet.

Are other sizes (nominal diameters) of the FlowTimer+ available?

Yes, see XL version (stainless steel, 1.5 inches, Kv = 24 m³ / h).

On request, the valve sizes DN15 - DN50 (IG 1/2 - IG 2 inches) with a Kv value of 4 - 40 m³ / h are available.

However, a 3/4 inch standard size with a Kv value of 8.0 m³ / h installed by means of reductions is rather oversized for most applications, since no further sensors additionally impair the flow.
