3.1 Function
The ceramic measuring cell is a dry measuring cell i.e. the pressure acts directly on the
robust, ceramic process isolating diaphragm of the Waterpilot FMX21. Potential changes
in air pressure are guided via a pressure compensation tube through the extension cable to
the rear of the ceramic process isolating diaphragm and are compensated for. A pressuredependent change in capacitance, caused by the movement of the process isolating
diaphragm, is measured at the electrodes of the ceramic carrier. The electronics unit then
converts this to a signal that is proportional to the pressure and linear to the level.

5.2 Additional mounting instructions
• Cable length
– Customer-specific in meters or feet.
– Limited cable length when performing installation with freely suspended device with
cable mounting screw or mounting clamp, as well as for FM/CSA approval: max. m/ft.
300 m (984 ft).
• Sideways movement of the level probe can result in measuring errors. For this reason,
install the probe at a point free from flow and turbulence, or use a guide tube. The
internal diameter of the guide tube should be at least 1 mm (0.04 in) greater than the
external diameter of the selected FMX21.
• To avoid mechanical damage to the measuring cell, the device is equipped with a
protection cap.
• The cable must end in a dry room or a suitable terminal box. The terminal box from
Endress+Hauser provides optimum protection from the effects of humidity and weather
conditions and is suitable for outdoor installation→ 118.
• Cable length tolerance: < 5 m (16 ft): ±17.5 mm (0.69 in); > 5 m (16 ft): ±0.2 %
• If the cable is shortened, the filter at the pressure compensation tube must be
reattached. Endress+Hauser offers a cable shortening kit for this purpose
(documentation SD00552P/00/A6).
• Endress+Hauser recommends using twisted, shielded cable.
• In shipbuilding applications, measures are required to restrict the spread of fire along
cable looms.
• The length of the extension cable depends on the intended level zero point. The height
of the protection cap must be taken into consideration when designing the layout of the
measuring point. The level zero point (E) corresponds to the position of the process
isolating diaphragm. Level zero point = E; tip of probe = L (see the following diagram).

1 Fieldgate FXA520
2 Multidrop connector FXN520
3 Cerabar
4 Waterpilot FMX21
For applications in which condensation may occur, the use of an absolute pressure probe is
recommended. For level measurement using an absolute pressure probe, the measured
value is affected by fluctuations in the ambient air pressure. To correct the resulting
measured error, you can connect an external absolute pressure sensor (e.g. Cerabar) to the
HART signal cable, switch the Waterpilot to burst mode and operate the Cerabar in "Electr.
Delta P" mode.
By switching on the "Electr. Delta P" application, the external absolute pressure sensor
calculates the difference between the two pressure signals and can thus determine the
level precisely. Only one level measured value can be corrected in this way.
If using intrinsically safe devices, the regulations which apply to interconnecting
intrinsically safe circuits as outlined in IEC 60079-14 (proof of intrinsic safety) must
be observed.
6.7.5 Connecting an external temperature sensor/temperature head transmitter for density compensation
The Waterpilot FMX21 can correct measured errors that result from fluctuations in the
density of the water caused by temperature. Users can choose from the following options:
Use the internally measured sensor temperature of the FMX21
The internally measured sensor temperature is calculated in the Waterpilot FMX21 for
density compensation. The level signal is thus corrected according to the density
characteristic line of the water.
Use the optional internal Pt100 temperature sensor for density compensation in a
suitable HART master (e.g. PLC)
The Waterpilot FMX21 is available with an optional Pt100 temperature sensor. Endress
+Hauser additionally offers the TMT182 temperature head transmitter to convert the
Pt100 signal to a 4 to 20 mA HART signal. The temperature and pressure signal is
requested by a HART master (e.g. PLC), where a corrected level value can be generated
using a stored linearization table or density function (of a chosen medium).

Use an external temperature signal which is transmitted to the FMX21 via HART
burst mode
The Waterpilot FMX21 is available with an optional Pt100 temperature sensor. In this
case, the signal of the Pt100 is analyzed using a HART-compliant (min. HART 5.0)
temperature head transmitter that supports burst mode. The temperature signal can thus
be transmitted to the FMX21. The FMX21 uses this signal for density correction of the
level signal.
The TMT182 temperature head transmitter is not suitable for this configuration.

Without additional compensation due to the anomaly of water, errors of up to 4% may
occur at a temperature of +70 °C (+158 °F), for example. With density compensation, this
error can be decreased to 0.5 % in the entire temperature range from
0 to +70 °C (+32 to +158 °F).
