0. Introduction
0.1 General
0.1.1 Description of device
0.1.2 Legal matters
The OPTIFLEX 1300 C gauge is designed solely for measuring the distance, level, interface, mass and
volume of liquids, pastes, slurries, granulates and powders.
OPTIFLEX can form part of an overfill protection system as defined in WHG if ordered with the appropriate
options.
The OPTIFLEX 1300 C is KROHNE's latest 2-wire TDR (guided-pulse) level-measurement gauge.
Using its new third-generation electronics, the gauge emits signals with a small pulse width, large bandwidth
and short signal rise and fall times. When the gauge processes the signal, a higher signal amplitude is
achieved which ultimately results in sharper resolution and higher accuracy.
TDR gauges use a probe to guide a signal to the surface of the measured product(s). With a choice of 6
probes, OPTIFLEX is capable of measuring most materials in very difficult conditions.
The OPTIFLEX 1300 C can detect and measure thin interfaces-not much thicker than a 50 mm film of oil on
water in a large tank. This is a new-generation level meter with a wizard-driven setup, fully-potted electronic
subassemblies, an online help functions.
It is provided with a pictorial quick setup. You will not normally need this Handbook to install, set up and
operate the device. All menu items have an on-screen help function that is activated 15 seconds after the last
input. In the unlikely event of a failure, error icons appear on-screen. Clicking on the error icon in the
PACTware device tool manager software or by looking in the error record menu item in program mode using
the device screen wizard displays an error description, which normally is sufficient to rectify the problem. Only
in severe cases will you need to consult the error records.
Authorized personnel
Installation, assembly, commissioning and servicing must only be undertaken by KROHNE-trained personnel.
Maintenance which is considered relevant to safety in the sense of explosion protection must only be carried
out by the manufacturer, his agents or under the supervision of experts.

1.2 Location
1.2.1 All applications
Handbook OPTIFLEX 1300 C
General notes
This section covers positioning the process connection and installing the device.
Mount the OPTIFLEX 1300 C gauge on a suitable process connection on a tank or sump.
Check the following:
• nozzle position in relation to the tank walls and other objects inside the tanks. Note: this free space
around the probe will depend on the probe type selected - refer to later on in this section
• installation adapted to the application
For further information on installation and applications, refer to section 1.2.2: Location, liquid applications
and section 1.2.3: Location, solid applications. Refer also to section 1.3: Typical installations.
Hazardous areas
Refer to the special manuals supplied on a CD-ROM with the device.
Process connections
Check that:
• the tank process connection is level
• there is a good fit between the device's process connection and the nozzle
• the tank roof does not deform under the weight of the device
Process connection and entry pipes
Do not put the process connection close to the entry pipe!
Pouring the product directly onto the probe will give false readings!
Install deflector pipes if it is impossible to move the tank fitting away from entry pipe.
OPTIFLEX 1300 C 10
Handbook OPTIFLEX 1300 C
Threaded process connections
The simplest and most economic way is to mount the level meter directly onto the tank with a GAS or NPTthreaded connection.
Use a 50 mm or 2" open-end wrench or similar to screw the device onto the tank process fitting.
Nozzles
Nozzle height
Recommendation (especially for single probes and powder applications):
Do not fit a nozzle longer than its diameter.
Nozzles extending into the tank
Do not use nozzles that extend into the tank!
This will create disturbances - especially for single probes!
False readings
Do not let the probe touch the side of the nozzle. This will give a false reading.
where h = nozzle height and
d = nozzle diameter
Contact KROHNE for assistance if
this relationship cannot be
respected.
11 OPTIFLEX 1300 C
Handbook OPTIFLEX 1300 C
Product build-up
Product can accumulate under the nozzle: this may weaken the measurement pulse. Avoid cavities that
permit the build-up of deposits.
You can configure the level meter to attenuate the effects of this build-up.
For further information, refer to section 4.2.4: Setup, advanced setup. Follow the procedures for modifying
Gain and voltage amplitude of the level and/or interface thresholds.
For further assistance, contact the supplier.
Cable probes
Installing level meters with single or twin cable probes
1. Support the housing and the probe using two people.
2. Insert the probe by holding the device more than one meter above the opening to avoid over bending the
cable.
Do not over bend probe!
Risk of measurement error!
OPTIFLEX 1300 C 12
Handbook OPTIFLEX 1300 C
Probe straightness and avoiding entanglement
• The cable must be straight once inserted into the tank.
• The cable counterweight should not touch the bottom of the tank.
• The cable must be far from other objects (e.g. mixers) to avoid entanglement.
Rigid length, Lr, of single and twin cable probes
Installation relative to other tank components
Objects near to the probe that influence measurement accuracy
Install the process connection far from protruding objects such as:
• heating tubes
• sudden changes in tank cross section
• tank wall reinforcements and beams
• weld lines
• dip-stick pipes
13 OPTIFLEX 1300 C
Handbook OPTIFLEX 1300 C
Refer also to the diagram below.
Guided-radar (TDR) level meters generate electromagnetic fields when a measurement pulse is emitted.
This field is affected by any nearby (metallic) objects and these will weaken and potentially disturb the
emitted pulse.
A minimum distance is recommended depending on the probe type to be installed. See the illustrations
below for recommended free space dimensions. Alternatively, the fitter may use a reference chamber or
stilling well. However, the chamber must be smooth, i.e. no visible weld lines, with straight and vertical walls
to maintain the pulse strength and measurement accuracy.
Position far from other objects in tank!
Risk of measurement error!
Special note: coaxial probes
These probes can be used close to or touching objects or walls as the EM field generated by the probe is
contained within the probe’s outer sheath and cannot be affected by other installations in the tank.
However, the coaxial probe is limited to applications using clean products i.e. non-crystallizing, low-viscosity
products that do not have solids in suspension.
OPTIFLEX 1300 C 14
Handbook OPTIFLEX 1300 C
Minimum recommended free space around probe, by type
There is no beam angle for any probe type - the limits of the EM field run parallel to the probe because the
measurement pulse emitted by the device is guided.
Single probe
Double probe
Coaxial probe
15 OPTIFLEX 1300 C
Handbook OPTIFLEX 1300 C
Installing two devices on the tank
Single or double probes:
Install at least 1 meter or 3.3 feet from each other to avoid interference from neighboring electromagnetic
fields.
Coaxial probes
No minimum distancing restrictions.
1.2.2 Liquid applications
Two devices fitted close together: single cable probes (left) and coaxial probes (right)
General notes
Follow these instructions and those given in section 1.2.1: location, all applications.
Turbulent products
If liquid products are agitated or turbulent, probe bending can occur.
Avoid probe bending!
Risk of measurement error!
OPTIFLEX 1300 C 16
Always install the meter as far away as possible from the source of turbulence.
Anchor the probe if necessary to ensure it stays straight and vertical.
See the following table.

1.2.3 Solid Applications
Coaxial
Products with foam
The presence of foam (especially if highly conductive) may require the installation of a stilling well or bypass
chamber.
For further information, refer to section 1.3.3: Stilling wells and section 1.3.4: Bypass chambers.
Petroleum products
These products may be stocked in vessels with moving roofs. In this case install a stilling well according to
local standards, rules and regulations relative to the application and site. Refer also to section 1.3.3: Stilling
wells.
Positioning nozzles on conical silos
Position the connection on the roof at ½ x tank radius and with minimum nozzle height. This will avoid
damage due to bending and traction when the tank is being emptied and also give reasonable
measurements.
OPTIFLEX 1300 C 18
Handbook OPTIFLEX 1300 C
Traction forces
Anchoring probes in solid applications
We recommend that the probe should not be anchored to avoid excessive traction loads on the cable and
potential cable breaks.
As a rule, do not anchor probes in tanks over 10 meters or 33 feet high.
High tanks - do not anchor probe!
Risk of probe breakage!
Traction load is dependent upon the height and shape of the tank, product particle size & density, and the
rate at which the tank is emptied.
Cable maximum design loads
The Ø 8mm or 0.3" single cable will fail at loads greater than 3.5 T or 7700 lbs. There is also a risk of
damage to pressure-bearing components inside the housing assembly. If loads exceed the maximum
design load, please contact KROHNE immediately.

1.3.2 Tanks with concrete roofs
Concrete roof thickness
Install the device according to this rule;
Ød => t
where Ød is hole diameter and t is concrete thickness.
If this rule cannot be obeyed, install the device in a recessed mounting as shown below on the right.
Handbook OPTIFLEX 1300 C
1.3.3 Stilling wells
Applications
Use a stilling well for these applications:
• where instructions for normal tank installation, such as the distance from the tank wall or tank internals,
cannot be followed
• tanks with floating roofs for petro-chemical applications
• products with foam
• tanks with turbulent processes
23 OPTIFLEX 1300 C
Handbook OPTIFLEX 1300 C
Installation requirements
• the stilling well must be electrically conductive
• stilling well wall must be straight and smooth (surface roughness ±0.1 mm or 0.004")
• no abrupt changes in well diameter greater than 1 mm or 0.04"
• drill a pressure equalization hole in the stilling well above the maximum product level
• an opening in the base is normally sufficient for one-liquid applications
• if foam is not present, drill other holes along the length of the stilling well: this helps the product to
circulate, especially where there is more than one liquid. These must be small, widely spaced and
deburred
OPTIFLEX 1300 C 24
• probe counterweights in stilling wells: check that there is sufficient (but not too much) play between the
counterweight and the inside wall of the stilling well for the product to circulate
Handbook OPTIFLEX 1300 C
Tanks with floating roofs
Commonly used for petro-chemical applications. Install a stilling well.
1. Stilling well
2. Tank
3. Floating roof
4. Petroleum products
5. Well is fixed to tank base-no roof
deformation
6. Sediment
1.3.4 Bypass chambers
Use bypass chambers for applications where there are:
• too many protruding objects inside the tank
• agitators
These installations have the same requirements as stilling wells. Refer to section 1.3.3: Stilling wells.
1.3.5 Spherical tanks
Applications
Measurement of liquid petroleum gas (LPG) is a common application for TDR. It is stocked in spherical
tanks.

2.1 Wiring
2.1.1 General notes
Cable entry
Electrical connection is made through two cable entries located at the back of the housing. The cable
entries can be ordered with adaptors:
• M20 x 1.5
• ½NPT
• G ½
cable glands are only supplied with non-Ex and EEx ia-approved devices. You must supply the cable
glands for EEx d and FM-approved devices.
Access to terminals is via a blue threaded cover on the side of the housing. As the device is a 2-wire
instrument, the power supply and the output signal transmitted by the device use the same cable.
Reminder of wiring fundamentals
Power supply
• disconnect the power supply before wiring the device
Cables
• use metal cable glands and reinforced, shielded cable to minimize RFI (radio frequency interference)
• observe applicable local rules and regulations for wiring
• always use the cable entry facing the terminal
• avoid crossing or looping wires
• add sufficient length to make U-bends in the cable to provide water with run-off points*
• do not let the cable come into contact with hot or potentially hot surfaces such as the flange*
• avoid kinks in the cable close to the cable entry glands by adding sufficient cable length. Reinforce with
* especially where the cable exits a conduit near to the device.
and/or EMI (electromagnetic interference)
a metal sheath at this point, if necessary*
