2.13 Product description
The IQ + FLOW® series is one of the smallest mass flow sensors of its kind. Due to the use of micro system technology,
ultra compact flow controllers are realised with dimensions of only 20 x 40 x 60 mm. The (IQF) flow controllers are
able to measure and control flow rates of 10 ml
n
/min full scale (FS) up to 5000 ml
n
/min FS. The (IQP) pressure
controllers are available in ranges from 0.5 to 10 bar FS. The IQ + FLOW® series has a modular concept with
combinations of 20 mm footprint modules, available as single instruments, but also as multiple channel arrangements.
A very compact manifold (IQM) system can be constructed, with one multi-channel digital pc-board (per 3 channels) in
a single housing, optionally available with filters and/or shut-off valves.
Communication with the devices can be either in analog mode or digital over RS232 or RS485. Communication over
RS232 is established with the Propar (FLOW-BUS) protocol. With digital operation over RS485 a bus-system with
multiple instruments can be set up. Modbus RTU/ASCII and FLOW-BUS protocols are supported (some exceptions for
multi-channel versions, see section 3).
