Preliminary Datasheet
SLQ-HC60
Milliliter Flow Meter for Hydrocarbons
www.sensirion.com November 2008 Preliminary Information _ V0.81 1/6
1 Introduction SLQ-HC60
The SLQ-HC60 Liquid Flow Meter enables fast, non invasive measurements of liquid flow up to 80 ml/min. This
product line is especially suited for process monitoring applications in automation technology which require high
sensitivity in the milliliter range. It is suited for use with almost all hydrocarbons, as for example, alcohols, oils,
gasoline, diesel, etc. and many other chemicals. Excellent chemical resistance is ensured: The flow path of the SLQHC60
Liquid Flow Meters is formed by a simple, straight glass capillary. This Swiss made, non invasive flow meter is
based on Sensirion’s patented CMOSens® Technology (US Patent 6,813,944 B2). An internal fourth generation
MEMS sensor chip combines a thermal high precision sensor element with amplification circuits and digital
intelligence for linearization and temperature compensation on one single microchip – the product’s core element.
2 Sensing Performance
In Table 1 the flow sensor’s performance for use with Isopropyl Alcohol (IPA) is given. For other hydrocarbons the
values will be slightly different as the performance depends on the medium used. Due to the optimized output signal
the repeatability is nearly constant over a wide flow range. The repeatability depends on the integration timea of the
analog signal acquisition. Longer integration time leads to better repeatability of the flow measurement (see table 1).
The temperature compensation is optimized for use with IPA and shows very good performance for most
hydrocarbons and other media.

c With IPA, 2.5-80 ml/min, after conversion of the Vout signal via the logarithmic relation.
d Normal position: Horizontal Flow channel, connector horizontally.

www.sensirion.com November 2008 Preliminary Information _ V0.81 2/6
3 Output Signal and Media
Compatibility
3.1 Output Signal
The SLQ-HC60 flow meter comes with
an analog output (0…10V). Depending
on the media used, the output will be
about 5 Volt at zero flow. For positive
flow rates the output signal increases
logarithmicallya with the flow rate for
IPA (see figure 1). This signal
characteristic has the advantage that
the flow meter can be used at various
flow rates with a constant relative error
and makes measurements for a wide
spectrum of liquids possible.
3.2 Signal for Other Media
For other media but IPA the form of the
sensor signal will differ slightly as is
demonstrated in figure 2. When using
the sensor with other media but IPA,
ask Sensirion for advice on how to
handle the sensor signal to suit your
requirements.
Because of the drastically different
sensor response the sensor is not
suited for use with water or aqueous
solutions.
3.3 Maximum Flow Rate for Common Media
Due to the measurement principle, the thermal
properties of the medium determine the sensor
characteristics and the dynamic range of the device.
For most hydrocarbons and most other media this
range extends to about 80 ml/min. With reduced
performance even rates of 100 ml/min or higher can
be reached for some media. For low viscosity (< 1
centipoise) media the dynamic range can be limited
by turbulence.
The dynamic ranges for various media are given in
Table 2. For other media similar values can be
expected.
Attention: If unsure about your medium please contact Sensirion for assistance.
a The flow rate for IPA is given by Flow[ml/min] = (Exp[(Vout-5)/0.729]-1)/3 for positive flow rates, i.e. above 5V.
b At reduced requirements on accuracy (repeatability for other media but IPA) and exchangeability of sensors.

www.sensirion.com November 2008 Preliminary Information _ V0.81 3/6
3.4 Exchangeability
Every SLQ-HC60 is calibrated for IPA. This makes the sensors also exchangeable for use with other media, meaning
that once the sensors are characterized for a particular medium the same values can be used for further sensors.
Depending on the media, variations between sensors of 6– 20% are typical.
4 Cleaning
Due to the measurement principle the sensor is sensitive to deposits on the inside of the sensor’s capillary.
Especially when changing from one liquid to another sufficient cleaning steps have to be performed to avoid nonsoluble
remainders on the capillary wall. Inadequate cleaning can lead to an offset and low repeatability. The
cleaning procedure has to efficiently remove contaminations from the borosilicate glass surfaces. This is the material
which is used for the straight flow channel inside the flow meter.
Any form of mechanical cleaning has to be avoided. This will easily damage the internal capillary.

5.3 Fluidic Connections
The repeatability of the measurement depends on a laminar flow of the liquid. Especially with low viscosity media
improper connections to the sensor can unnecessarily reduce the maximum flow rate. Tubing with an inner diameter
of less than 1.8 mm should be avoided. Make sure that the tubing has been cut properly.
