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
v
-value of
the orifice the flow is calculated using the k
v
formula. The k
v
-
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
v
-value is also possible.
Apart from differential pressure and flow measurement the
BasicMes-2 has the following functions:
• Two temperature sensor inputs for simultaneous (using two
sensors) or successive (using one sensor) temperature
measurements
• Data logging function with programmable interval and dura-
tion
• Leakage test with programmable test pressure and duration
• 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)
Features
• Easy to use device with compact dimensions
• Large backlit colour display
• Integrated valve database
• Bypass for venting of hoses and zero calibration
• PC connectivity with software included
• Robust case for device, accessories and optional pocket
printer
• Magnet on back to attach to metal surfaces
