IMPORTANT SAFETY AND COMPLIANCE INFORMATION
This section provides important information for your safety and product compliance.
USA, FCC, Part 15 spectrum compliance
This device complies with Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation.
Operation is subject to the following two conditions:
This device may not cause harmful interference.
This device must accept any interference that may cause undesirable operation.
This device must be installed to provide a separation distance of at least 7.9 inches (20 centimeters) from all
persons to be compliant with regulatory RF exposure.
USA, FCC Class B-Part 15
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio or TV technician for help.
Modifications and Repairs
To ensure system performance, this device and antenna shall not be changed or modified without the express
approval of Mesura Metering. Per FCC rules, unapproved modifications or operation beyond or in conflict
with these instructions for use could void the user's authority to operate the equipment.

INTRODUCTION
The PRODIGI family of products is designed to measure the volume of gas of the second or third family (UNI
EN 437) at a maximum working pressure of 7.2 psi, and a maximum flow rate of up to 211,8 ft3/h. The meter
is equipped with an ultrasonic measuring sensor, the performance is ensured by two lithium batteries
(described in the chapter "BATTERY MAINTENANCE"). The device, besides the volume measurement, allows
the remote reading and the remote control of the gas flow without the aid of external devices, but by means
of different transmission technologies that are indicated below. This document provides information on the
characteristics and use of the device, and is valid for all members of the family of PRODIGI products.
It is specified that the models listed below are identical from the point of view of construction, what varies
is the calibration procedure to which they have been subjected. Specifically, all four models PRODIGI,
PRODIGI 16, PRODIGI 25, PRODIGI 40 are intended exclusively for the measurement of natural gas (methane),
and differ only for the calibrated flow range.
While the PRODIGI LPG model is calibrated exclusively for the measurement of all types of LPG mixtures.
The different models differ in the following characteristics:
-Measured flow range
-Measured gas family
And they are classified according to the following scheme:
FORMAT -> PRODIGI XX
Here are the different models available:
XX -> identifies the measured flow range:
-PRODIGI16 -> 0,016 ÷ 2,5 m3/h (ex G16), NATURAL GAS
(Calibrated to measure from 0,016 m3/h to 2,5 m3/h, intended for natural gas measurement)
-PRODIGI 25 -> 0,025÷ 4 m3/h (ex G25), NATURAL GAS
(Calibrated to measure from 0,025 m3/h to 4 m3/h, intended for natural gas measurement)
-PRODIGI 40 - > 0,04÷ 6 m3/h (ex G40), NATURAL GAS
(Calibrated to measure from 0,04 m3/h to 6 m3/h, intended for natural gas measurement)
-PRODIGI -> 0,016÷ 6 m3/h, NATURAL GAS
-(Calibrated to measure from 0,016 m3/h to 6 m3/h, intended for natural gas measurement)
-PRODIGI LPG -> 0,016÷ 6 m3/h, LPG
-(Calibrated to measure from 0,016 m3/h to 6 m3/h, intended for the measurement of any type of LPG
mixture)
These models can be supplied with one of the following transmission technologies:
-NBIoT / LTE
-LoRa 915 MHz

DATA MEASUREMENT AND RECORDING
The measurement is acquired through an ultrasonic sensor (static sensor), this is then processed by the
control electronics, saved in the volatile memory of the meter and sent to the gas company via the
transmission protocol.
The meters of the PRODIGI family are also equipped with a non-volatile memory on which the data is
recorded at a regular interval of 60 minutes.
PRODIGI meters implement the following services:
-Dynamic multi-tariff capacity
-Measurement and load profiles
-Data collection and recording
As far as data recording is concerned, the PRODIGI meters implement the following services:
-Detection and reporting of faults
-Functional requirements - Event logging
-Functional requirements - Diagnostics and alarms
DATA TRANSMISSION
The meters of the PRODIGI family are equipped with two communication interfaces, one local and one
remote.
LOCAL: The meter is equipped with an optical port according to EN 62056-21, and requires an external device
