Tokyo Keiki MW-10 Quick Installation Manual

Quick installation guide for MW-10/MW-11
Read this instruction carefully to use the device correctly. For detailed information, please refer to the instruction
manual for the radar level gauge itself, "Non-contact Radar Level Gauge MW-10 MW-11 User's Guide".
(document number: KF24-001*)
1. Site Check
Please install level gauge avoiding any obstructions in
the following beam area, which may any cause of
disturbance reflection.
Model 10m
Distance Model 15m
[m] Model 30m
Beam angle=
5
10
15
30
50
100
It is recommended not to install the obstructions in an
area of twice beam angle for more stable
measurements.
2. Installation Tips
For stable measurement, please keep the mounting
parallel to the level plane to get better signal strength to
liquid surface.
The following cases will affect measurement
performance:
(1) The full performance is not achieved in the level
gauge installed incorrectly.
(2) Obstructions in the beam area will reduce reflection
signal and decrease and narrow the measurable
range.
(3) Deposit buildup on the antenna, foaming on liquid
surfaces may affect measuring range and
performance.
(4) Compared to calm liquid surfaces, measuring
ranges of turbulent surfaces are reduced due to
poorer reflection.

3. Mechanical Installation
(If bracket used then follow the below steps)
Hexagon wrench (5mm) is required to assemble the
mounting bracket.
(1) Fit the recessed part in the mounting bracket to the
projected part in the case.
(2) Tighten up the bolt with hexagon wrench. Two bolts
are boxed together with the mounting bracket.
(3) Install at customer's preferred location using 4 holes
of the bracket for installation.
NOTE: For stable measurements, keep the mounting
bracket parallel to the level plane to get better
signal strength to liquid surface.
NOTE: The mounting bracket assembly for 50m/100m
model is the same as for 10m/15m/30m model.
