Sensors fit on the outside of the pipe, so the pipe stays closed.
How it connects
WiFi
Wireless over your WiFi network, with readings stored in the cloud.
Works with MeterTube, the pFlow app and cloud platform.
Pipe sizes
DN20–DN32
DN is the nominal pipe size, roughly the inside diameter in millimetres.
Why MP
MP in short.
The MP series flow sensor simplifies operation while ensuring quality. Its integrated clamp-on structure installs quickly: clamp it onto the pipe and lock it with a nylon cable tie. WiFi communication stores the data in the cloud, where users can access and manage it anytime from a phone or PC.
Where it is used
Municipal garden irrigation
Building water management
Household water management
Collective dormitories
Water management
Aquaculture
Farm irrigation
Automatic car washing
How it works
Sound with the flow arrives sooner.
Two sensors on the same side of the pipe take turns sending sound through the water. Sound travelling with the flow arrives slightly sooner than sound travelling against it; the meter turns that time difference into flow, which is why it needs to know your pipe.
A smooth metal surface. Clean the spot, add coupling gel, then clamp the sensor on.

What these terms mean
DN
Nominal pipe size, roughly the inside diameter in millimetres (DN50 ≈ 50 mm).
Clamp-on
Sensors strap to the outside of the pipe. No cutting, no shutdown for installation.
PoE
Power over Ethernet: one network cable carries power and data.
LoRaWAN
Long-range, low-power wireless. Readings travel through a gateway to a network server.
Modbus RS485
A wired connection widely used by building and industrial control systems.
4–20 mA
An analogue signal where the current represents the reading.
