1.2 Theory of Operation
The Wireless Triaxial Tiltmeter is a low touch Internet of Things (IoT)
device. It is designed to be as simple as possible to install and activate —
set and forget. Data is retrieved from the device via our cloud-based platform
or via API to yours using the integrated LTE-M (CAT-M1) cellular
communications. The device also uses LTE-M for time stamping to within 1
second for comparison of data between nodes.
The device sensor is always monitoring for events, and can be continuously
monitoring, or set to a triggered state to upload data within seconds. Remote
configuration is possible to change the acquisition and upload frequency via
the myViotel device management tool or API.

Contact Viotel for any support required.
2.3 Mounting Options
Viotel’s Wireless Triaxial Tiltmeter Node can be mounted in a number of ways.
The following is a list of recommended methods.
| MOUNTING | DESCRIPTION |
|---|---|
| 1. Side Mounting Holes | Side mounting points designed for M4 countersunk |
bolts or screws.
Up to 10G countersunk screws will fit in the M4 bolt hole.
2. Adhesive| The honeycomb backing plate provides the ideal surface area for
use of fast grab adhesives. The Tiltmeter can be removed leaving only the
backing plate in place.
Replacement backing plates can be ordered from Viotel (item # VFN-001)
3. Pole Mount| Threaded M3 holes in the backplate suitable for optional pole
mount bracket or mounting to a plate within an enclosure.
4. Two-Sided Adhesive| Clean and dry the mounting locations surface. Peel off
the red plastic layer on the back of the node and firmly press it onto the
required location. Keep the device and surface under this same pressure for
approximately 20 minutes (to achieve 50% bond strength in room temperature).
We suggest using this to assist with installation and in conjunction with a
physical coupling (Method 1).
2.4 Orientation Description
Figure 6 demonstrates the three internal orientation axes with respect to the Tiltmeter enclosure, where the positive end of each axis is annotated with the axis label. For example, the positive end of the x axis is at the right of the tiltmeter in the figure.
2.5 Rotation Description
Measurements made by the Tiltmeter are mapped to three angles calculated and
displayed in the device’s data section within the myViotel application. These
are ‘Angle between horizon and Z-axis’, ‘Angle between horizon and X-axis’,
and ‘Angle between Upwards and Y-axis’, and are explained below.
Angle between horizon and Z-axis
This ranges from -90 to 90 degrees. It measures the angle between the Z-axis
of the device to the earth’s horizon (the plane perpendicular to gravity). The
below images demonstrate rotations in this angle when you look at it side-on
if it was mounted portrait vertically on a wall, with connector pointing down.
Angle between horizon and X-axis
This ranges from -90 to 90 degrees. It measures the angle between the X-axis
of the device to the earth’s horizon (the plane perpendicular to gravity). The
below images demonstrate rotations in this angle when it is facing you while
mounted portrait vertically on a wall, with connector pointing down.
Angle between Upwards and Y-axis
This ranges from 0 to 180 degrees. It measures the angle between the Y-axis of
the device to the Upwards direction in the real world. The below image
demonstrates rotations in this angle when it is facing you while mounted
portrait vertically on a wall, with connector pointing down.
The same rotations
apply when viewing the Tiltmeter from side-on and considering the Y and Z
axes.
As a result of the ambiguity in the Y-axis angle, Viotel recommends that the ‘Angle between horizon and X-axis’ and ‘Angle between horizon and Z-axis’ angles are used for monitoring of a node installed in the recommended vertical portrait (connector pointing down) orientation.
Operating Instructions
3.1 Operation
By default, your Viotel Wireless Tiltmeter Node will be set to Sleep mode. To
change the mode that the tiltmeter is currently in, simply take the magnet
(Part 4) and tap it on the node (position as indicated in Section 2.1
Indicated Magnet Location).
All operations and LED indications refer to firmware version: 3.02.14, please
be aware future states may change some functionality.
| TAP INSTRUCTIONS | FUNCTION | DESCRIPTION |
|---|---|---|
| Tap once (while in Sleep) | Query Status | This will light up a blue LED to |
indicate the device is currently in Sleep mode.
Tap once (while Active)| Test Shots| The device will perform 10 record-and-
upload cycles of 3 minutes each. Once this data has been logged, the device
will return back to its standard operation.
Tap once, Tap again within 3 Seconds| Upload and change status| This will
cause the device to wake up and go into Active mode. As part of this process,
the node connects to the cloud and applies any new settings. The device is
fully Active and recording after a few minutes.
Table 4 How to switch between modes
3.2 Initial Site Set Up
You may be installing your tilt meter at a location with access constraints,
so it is important to ensure that you have set the device reading and upload
to a suitable initial frequency to both suit your initial data needs and such
that you can subsequently change the frequency in myViotel.
If the device is initially set to a long upload time frame – for example daily
uploads, it will not pick up any changes you make in myViotel until the next
upload cycle. Thus we recommend initially setting the device to a high upload
frequency so that you can review the data over the next few hours and then
make any adjustments you desire in myViotel and the device will then reflect
these changes within the next upload.
