1.2 Applications

1. Level measurement of liquids

The level transmitter 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.

PRODUCT FEATURES

2. Volume measurement

A conversion table (strapping table) function is
available in the configuration menu for volume or
mass 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.

1.3 Product family

OPTIFLEX 1100 C
for continuous measurement of liquids and solids up to 16 barg (232 psig) and +100°C (+212°F)

1

OPTIFLEX 1100 C is a 2-wire TDR level transmitter
for measuring distance, level, volume and mass of
liquids and solids. Its simple, compact design allows
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.

It is ideal for level measurement in buffer tanks,
collectors and simple process applications and silo
level monitoring in quarrying and agriculture.

1.5 Measuring principle

This Guided Radar (TDR) level meter has been developed from a proven technology called Time
Domain Reflectometry (TDR).

www.krohne.com 07/2019 - 4006447902 - TD OPTIFLEX 7200 R02 en

OPTIFLEX 7200 C/F/S/D

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 with an
intensity that depends on the dielectric constant, ε

dielectric constant and reflects the pulse back to the signal converter at 80% of its original
intensity).

The device measures the time from when the pulse is emitted to when it is received: half of this
time is equivalent to the distance from the reference point of the device (the flange facing) to the
surface of the product. The time value is converted into an output current of 4...20 mA and/or a
digital signal.

Dust, foam, vapor, agitated surfaces, boiling surfaces, changes in pressure, changes in
temperature and changes in density do not have an effect on device performance.

The illustration that follows shows a snapshot of what a user would see on an oscilloscope, if the
level of one product is measured.

PRODUCT FEATURES

The dielectric constant of the top liquid must be less than the dielectric constant of the bottom
liquid. If not, or if there is too small a difference, the device may not measure correctly.

13 Received EM pulse (distance to the interface of 2 liquids)

Level measurement principle (TBF measurement)

If products have a very low dielectric constant (εr<1.6), only a small part of the EM pulse is
reflected at the surface of the product. Most of the pulse is reflected at the probe end. TBF (tank

bottom following) mode is used to measure the distance to the product surface.

TBF mode (indirect measurement) compares:

• The time for the pulse to go to the probe end and go back to the converter when the tank is
empty.

• The time for the pulse to go to the probe end and go back to the converter when the tank is
full or partially filled.

10

The level of the product in the tank can be calculated from the time difference.
