Area of use

Midor is designed to create hydronic balance in heating and cooling systems. It can be used for measuring pressure, flow and temperatures in a system.
Midor can calculate complicated heating systems with several branches by simulating a hydronic system with balancing calculations based on two measurements in each branch.


Midor is a balancing instrument you control via your android or apple unit. You can measure temperature, pressure and flow. Midor can be used in large-scale projects in which it can divide the flow proportionally with double sensors or reach valves a long way out in the installation by means of a network of routers.
With Midor, almost anything is possible. At MMA we have developed our own applications in the software, where you can see current valve authority or monitor the pressure drop in individual circuits. The software is always available on and App store.
Midor’s high precision means that we can recommend measurements down to 2 kPa. This contributes to energy-efficient balancing.
Midor has a number of important functions which makes the system easy to use.
Midor consists of two separate units: a measuring unit for pressure, fl ow, and a calculation unit for displaying results and analysing data.
The measuring unit is extremely robust and has a sturdy frame. Inside the measuring unit there is a hydronic component with an integrated differential pressure sensor; the values shown by this sensor are used for precise data processing.
The flow meter automatically corrects the fl ow of different types of media being measured, such as the coolant in a cooling system.

NOTE! Midor is not frost-resistant. Always make sure to store your unit in a frost-free place.
