L900 MIU Pit Installation and Maintenance Guide 1Chapter 1: Product DescriptionThis chapter provides a general description of the L900™ Pit meter interface unit(subsequently referred to as L900 MIU).The L900 MIU by Neptune is a compact electronic device that collects meterreading data from an encoder register. It then transmits the data for collection bythe meter reader. A walk-by handheld unit (HHU), mobile unit, R900®Gatewaycollector, or LoRa®(Long Range) collector receives the data and stores it to bedownloaded into the utility billing system for processing.The L900 MIU is easily installed and operates within a radio frequency (RF)bandwidth which does not require an operating license. Because the L900 MIU canbe mounted as far as 500 feet from the encoder register, optimum broadcast signalstrength is obtainable, ensuring a high percentage of accurate, one-pass readings.Figure 1 – L900 MIU - PitThe L900 MIU meets FCC regulations Part 15.247, allowing higher output powerand greater range. The L900 MIU uses frequency-hopping, spread-spectrumtechnology to avoid RF interference and enhanced security. The L900 MIU readsthe encoder registers at 15-minute intervals and transmits a mobile message thatincludes the meter reading data and the unique nine-digit L900 MIU ID every 20seconds. This allows the meter to be read by an HHU or mobile data collectionunit. The L900 MIU also transmits a high power fixed network message everyseven and one-half minutes on an interleaved basis to an R900 Gateway.In addition to the mobile message that is transmitted every 20 seconds and thefixed network message that is transmitted every seven and one-half minutes, theL900 MIU is capable of supporting fixed network using a LoRa network.
The fixed network message that transmits for use on a LoRa network is sent everythree hours.The L900 MIU is designed to offer advantages to utility organizations of all sizes:lIncreases meter reading accuracy.lEliminates infrastructure concerns and the burden of managing collectiondevices.lEliminates “hard-to-read” meters.lProtects utility liability by increasing meter reader safety.lRequires no programming.Product DescriptionThis section gives an overview of the L900 MIU.L900 MIU ProgrammingThe L900 MIU does NOT require field programming.RF Protocol Error DetectionThe RF protocol is comprised of a header, data packet, and an error detectionmechanism that reduces the erroneous data.RF Frequency Control AlgorithmThe L900 MIU’s frequency-hopping, spread-spectrum has a sequence of at least 50different channels for transmitting data. Associated with the 50 channels are 50frequencies that can be pre-selected in a pseudo random manner. These 50frequencies are coded into the software.The L900 MIU avoids 914 MHz to prevent collision with the Advantage probe.RF Transmission Period and RandomnessThe random period generation uses the same random seed created for the channeldefinition to generate the transmission randomness. The randomness algorithm isdefined so that no two consecutive transmissions from two L900 MIUs interferewith one another.Low Battery RF EmissionsThe L900 MIU stops RF transmissions when the battery discharges below thenormal operating voltage.2 L900 MIU Pit Installation and Maintenance GuideChapter 1: Product Description

The L900 MIUis activated using the Trimble®Nomad®and R900®Belt Clip Transceiver(R900 BCT) and is explained in more detail in the following section.The L900 MIU stores consumption in hourly intervals for a rolling total of 96 days.This is equal to 2,304 hourly intervals of consumption. The data logging data isextracted through RF activation. The RF activation allows the utility workers tovisit the location and extract the data without physically interacting with the meteritself. This limits the worker’s exposure to animals or other dangerous situations.The extraction process, once started, takes approximately 30 seconds. Theactivation is done through the HHU connected to the R900 BCT via Bluetooth.The activation signal is sent by the R900 BCT to the L900 MIU which in turnsends the data intervals to the R900 BCT and are saved in the HHU.Accessing Data LoggingComplete the following steps for data logging.1. From the host software home screen on the HHU, click MENU. See Figure 46.Figure 33 – HHU Home Screen
