D2O FL1 Product Manual - 1

The Zepiro® D2O® (Direct-To-Orbit) FL1 is a satellite telemetry solution for

digital, pulse type, flow meters. It is ideally suited to use in remote or diicult

to access areas and can transmit from virtually any surface location globally

within satellite service areas.

It is a low-powered device designed for endurance, maintenance-free

monitoring applications with the included battery capable of providing power

for up to three years.

The D2O FL1 records hourly flow totals and data messages are created and

queued for satellite transmission periodically throughout the day, each

containing up to 7 hourly measurements. Messages are sent via a low-earth

orbit satellite network back to a terrestrial ground station. From there Zepiro’s

servers securely recompile the data packets to readable formats and forwards

the data to the end user for analysis.

2.1 INTRODUCTION

The D2O will transmit a range of data during its normal operation. In

addition to the regularly transmitted core flow meter data, the D2O will

also periodically transmit system and notification data relating the ongoing

operation and health of the device.

Data is optimised for transmission through the satellite network, and is then

uncompressed and formatted for analysis by the Zepiro servers before being

presented for end use.

The following tables indicate the data that will be transmitted at various times

during the D2O deployment.

DATA DESCRIPTION

Engineering Units The currently set engineering unit associated with the readings (L, kL, ML, Gal, kGal, MGal, m³)

Total Flow Volume A timestamped total flow volume reading (in engineering units) since the D2O’s initial deployment

Data Points Up to 7 hourly measurements, each representing the average flow rate per hour. Each measurement is

individually timestamped. The number of measurements included in an individual message will vary within a

24hr period based on synchronisation time settings

Device Integrity Info Basic information to indicate that the system is performing as intended without alert, tamper or fault

2.2 FLOW METER DATA

This data includes the readings and parameters associated with the flow

meter input, as well as indicates the data integrity. This data is typically

transmitted 4 times a day.

DATA DESCRIPTION

Battery Information Includes the current battery voltage and remaining charge level as a percentage

Module Temperature The temperature of the PCB board within the D2O enclosure in Degrees Centigrade

Current GPS Coordinates The Global Positioning System (GPS) Latitude and Longitude coordinates in 0.001 resolution

RSSI The Receiver’s background noise level or RSSI (Received Signal Strength Indicator) in dBm

Queue The remaining storage space in the transmission queue in bytes (0 - 320 bytes)

Sample Counter The total number of samples taken since the D2O’s initial deployment

2.3 SYSTEM DATA

System data includes diagnostic information about the D2O and is key to

understanding how the unit is performing. This data is continually updated

and is usually transmitted twice a week.

D2O FL1 Product Manual - 5

DATA DESCRIPTION

Alert Data Reports on alerts (New Battery, Tamper, Login, Memory, Other), including the time that the first alert type was

recorded, the elapsed time from first alert to most recent alert, the types of alert recorded and the total number

of alerts recorded (of any type).

Tamper Data Reports the time activated when the internal tamper switch opens (activates)

Fault Data Reports on faults (Wire Fault, Temperature, Sensor, Failure, Other), including the time that the first fault type

was recorded, the elapsed time from first fault to most recent fault, the types of fault recorded and the total

number of faults recorded (of any type).

2.4 NOTIFICATIONS DATA

Notification data includes information on any alert, tamper or fault the D2O

may be experiencing. This data is only transmitted if there is an active alert,

tamper or fault.

3.1 ANTENNA BASICS

Before deciding on a location to install your D2O unit it is important to

understand how the D2O operates.

The D2O uses electromagnetic radio waves to communicate with the

individual satellites in a nano-satellite constellation. Transmission and

reception of these waves is facilitated by the D2O’s antennas.

The D2O knows when these orbiting satellites will be transiting through a

visible section of sky and transmits messages during this window.

The vertical orientation of the D2O’s antennas means that it has the strongest

transmission and reception abilities in a range perpendicular to the Antenna,

emanating in a radial pattern. When a satellite passes through the sky

between the horizon, and up to approximately 75° from the horizon the

D2O has the greatest opportunity for a successful transmission or reception.

Satellite passes below 20° above the horizon have a lower probability of

transmission.

Directly above the Antenna, between 75° and 90° (straight upward), the

transmission and reception abilities of the Antenna are poor.

Most satellite passes will occur across a partial section of sky. This is due to

the orbital pattern of the satellites and their relationship to the D2O’s position

on earth.

Having a clear line of sight to as much of the sky as possible, and in all

directions, will minimise the risk of missed transmission opportunities.

window of approximately 75° from the horizon.
