OPTIFLEX 1100 C
1.1 The cost-effective TDR solution
OPTIFLEX 1100 C is a 2-wire TDR level meter for measuring distance, level, volume and mass of
liquids and solids. Its simple, compact design allows service technicians to quickly assemble the
probe and attach it to a threaded connection. It is an affordable solution for applications that do
not require a high level of accuracy and is also an excellent alternative to traditional level
controls such as RF Capacitance, conductive and DP transmitters.
PRODUCT FEATURES 1
1 Aluminium housing with optional LCD display screen
2 Converter is rotatable and removable under process conditions
3 Threaded connection (NPT or G)
4 Choice of cable or coaxial probe
5 2-wire loop-powered level meter
Optional integrated display
The display can be ordered with the device or as an accessory. It shows measurement data on a
128 × 64 pixel screen. The configuration menu permits the device to be set up in a small number
of intuitive steps.

OPTIFLEX 1100 C
1.2 Applications
1. Level measurement of liquids
2. Level measurement of solids
PRODUCT FEATURES 1
The level meter can measure the level of a wide
range of liquid products on a large variety of
installations within the stated pressure and
temperature range. It does not require any
calibration: it is only necessary to adapt the probe
length and do a short configuration procedure.
3. Volume measurement
The level meter has a Ø4 mm / 0.15¨ single cable
probe for measuring powders and granulates in
silos up to 10 m / 32.8 ft high. It does not require any
calibration: it is only necessary to adapt the probe
length and do a short configuration procedure.
A strapping table function is available in the
configuration menu for volume measurement. Up to
30 volume values can be related to level values. For
example:
Level 1= 2 m / Volume 1= e.g. 0.7 m³
Level 2= 10 m / Volume 2= e.g. 5 m³
Level 3= 20 m / Volume 3= e.g. 17 m³
This data permits the device to calculate volumes
between strapping table entries.

1.4 Measuring principle
This Guided Radar (TDR) level meter has been developed from a proven technology called Time
Domain Reflectometry (TDR).
The device transmits low-intensity electromagnetic pulses of approximately one nanosecond
width along a rigid or flexible conductor. These pulses move at the speed of light. When the
pulses reach the surface of the product to be measured, the pulses are reflected back to the
signal converter.
The device measures the time from when the pulse is transmitted to when it is received: half of
this time is equivalent to the distance from the reference point of the device to the surface of the
product. The time value is converted into an output current of 4...20 mA.
Dust, foam, vapour, agitated surfaces, boiling surfaces, changes in pressure, changes in
temperature, changes in dielectric constant and changes in density do not have an effect on
device performance.
