1 Scope of this manual
1.1 Introduction
This manual covers the LIQUI-FLOW mini series mass flow meters for micro fluidic flow. An example of the
instrument is shown in the picture below. This manual includes product information, installation instructions,
operation, maintainance and troubleshouting.
LIQUI-FLOW mini instruments are one of the smallest micro fluidic Mass Flow Meters (MFM) of its kind. The very
compact instruments with dimensions 20 x 40 x 60 mm are capable of measuring ultra low flow rates in ranges
starting from 1.5…30 mg/h up to 12…600 mg/h, based on water. The straight, duplex steel sensor tube (W1.4462)
has an internal volume of less than 1 mm
3
and operates on the thermal measuring principle. Due to its high
pressure rating of max. 1200 bar (17400 psi) the MFM is suited for HPLC systems. The instruments are equipped
with a microprocessor-based printed circuit board, offering high accuracy and excellent temperature stability. The
RJ45 connection is used for power supply and for both analog and digital (RS232) communication.
