HANDHELD FLOW MEASUREMENT COMPUTER
Application
The BasicMes-2 is a handheld measuring computer for flow
measurements in hydronic heating and cooling systems.
The BasicMes-2 measures the differential pressure over an
orifice, for example a valve seat. Together with the k
the orifice the flow is calculated using the k
value of all Honeywell balancing valves as well as some
common valves of other manufacturers are stored in an internal
database. Manual input of the k
Apart from differential pressure and flow measurement the
BasicMes-2 has the following functions:

sensors) or successive (using one sensor) temperature
measurements
• Data logging function with programmable interval and dura-
tion

• Memory to save measured values
• PC connectivity to download measured data from the device
onto a PC including PC user software
• Print function in combination with optional pocket printer
(accessory)
