1.1 Software history
"Firmware revision" agrees with NAMUR NE 53. It is a series of numbers used to record the
revision status of embedded software (firmware) in electronic equipment assemblies. It gives
data on the type of changes made and the effect that changes have on compatibility.
Data about software revisions is shown in the DTM for PACTware™. For more data,. If it is not
possible to refer to data in the software, record the serial number of the device (given on the
device nameplate) and speak to the supplier.

1.2 Intended use
CAUTION!
Responsibility for the use of the measuring devices with regard to suitability, intended use and
corrosion resistance of the used materials against the measured fluid lies solely with the
operator.
INFORMATION!
The manufacturer is not liable for any damage resulting from improper use or use for other than
the intended purpose.
This radar level transmitter measures distance and level of liquids. It does not touch the
measured product.
This radar level transmitter can only be used if it is correctly installed and aligned on a bypass
chamber or a stilling well. The bypass chamber or stilling well must be metallic and electrically
conductive. The stilling well must installed in a metal or reinforced concrete tank to prevent
radio frequency interference.

2.2 Device description
OPTIWAVE 1010 is an FMCW radar designed for use with the BM 26 Advanced (a magnetic level
indicator or MLI), bypass chamber or stilling well. If the device is used with an MLI, it measures
the distance to the float. If the device is used with a bypass chamber or stilling well, it measures
the distance to the surface of the liquid. Radar is a non-contact technology. For more data about
the measuring principle, refer to
Measuring principle

If there are parasitic signals, the device will not measure correctly. Parasitic signals are caused
by sudden changes in bypass chamber diameter in the path of the radar beam.

3.8 Stilling wells
Install the device in a metal stilling well if the radar level transmitter is attached to the top of the
tank and not on the top of a magnetic (bypass) level indicator or a bypass chamber.
CAUTION!
If the stilling well has liquid circulation holes, then the tank must be made of metal or reinforced
concrete to prevent radio frequency interference.

CAUTION!
Installation requirements
•
The standpipe must be electrically conductive.
•
The standpipe must be straight. There must be no sudden changes in internal diameter
greater than 1 mm / 0.04
•
The standpipe must be vertical.
•
Recommended surface roughness: <±0.1 mm / 0.004¨.
•
Make sure that there are no deposits at the bottom of the standpipe.
•
Make sure that there is liquid in the standpipe.

General notes
Installation in tanks containing one liquid and foam
• Drill an air circulation hole (max. Ø10 mm / 0.4¨) in the stilling well above the maximum level.
• Remove the burr from the hole.

3 INSTALLATION
Installation in tanks containing one liquid or more without foam
• Drill an air circulation hole (max. Ø10 mm / 0.4¨) in the stilling well above the maximum level.
• Drill 1 or more liquid circulation holes in the stilling well (if there is more than 1 liquid in the
tank).
i These holes help the liquid to move freely between the stilling well and the tank.
• Remove the burr from the hole.
3.9 How to attach the weather protection to the device
The device and the weather protection option are supplied disassambled in the same box. You
must attach the weather protection when you install the device.
