The balancing instrument is connected to the pressure test ports.
The instrument is pre-programmed with the characteristics of all our adjustment valves and measuring stations. Other valve manufacturers’data is also included in the instrument. Values for pressure drop and flow can be read on the display. If you do not have access to the MMA instrument other common instruments for measuring pressure drop can be used.The flow can then be read from the pressure drop diagram found in the instructions.
