The reading units are intended for close or distant reading of data from heat cost allocators or radio modules for water meters. For reading of devices with radio transmitter, customers can choose between walk- by reading systems, and between central reading systems, which will enable daily readings, information about manipulation attempts, backflow on the water meters etc.
The RST-869V-3 antenna is intended for use with 868 MHz radio sets. The antenna has circular polarization, low VSWR and is less directional. The radiators are located in a plastic housing. An additional handle allows the antenna to be carried easily. The antenna is equipped with an N-female connector.
The RFU 40 is a data reading unit for receiving radio data from E-ITN 30 heat cost allocators and radio modules for residential water meters E-RM 30 broadcasting with APATOR METRA protocol. RFU 40 is an independently working and battery powered device. This reading unit is designed to be used with a mobile device running Android v4.2 or higher. Three LED indicators are located on the front panel that display state of the Bluetooth module, incoming radio data and battery level.
Radio reading unit RFU 35 is intended for contactless reading of data transmitted by heat cost allocators E-ITN 30 and radio modules for water meter E-RM 30. Unit can be connected to computer (usually notebook / netbook) using standard USB port. Unit can be used with supplied omnidirectional rod antenna or, to increase the reading range, with optional panel antenna ZZ P-868.
Central reading system CRS 40 V2 is designed for data reading from radio heat cost allocators (E-ITN 30) and radio modules for water meter (E‑RM 30) transmitting in the 868 MHz ISM band. The reading network consists from one or more collecting units A (concentrator) for data reading and one control unit B (coordinator) that coordinate the reading network and send the data via Internet (Ethernet, Wi-Fi or GSM) to the remote operator.
Unit IRU 10.00 is used for data reading from the electronic heat cost allocators E-ITN 10, 20, 30 and radio modules for residential water meters E-RM 30 via infra-red (IR) interface. Also basic service of radio module E-RM 30 (without LC Display) is possible to provided with IRU 10.00 (switching between modes and to display set parameters or module functions). Read data are transmitted via serial interface RS-232 to PC for further processing.
Reset unit IRU 10.00 is used for fast and convenient reset of consumptions in radio modules for residential water meters E-RM 30 via infra-red (IR) interface. Reset unit consists of a two part plastic casing, where electronic parts including batteries are located. Cover parts are connected with screw, after screw release upper side of the cover can be removed to replace the batteries. At the top of the reset unit, reading head with transmitting (and also receiving) IR diode and LC Display is located On the left side of the reset unit, operation button and serial port connector (this connector has no function here).
Unidirectional panel antenna ZZ P-868 is additional equipment for radio reading unit RFU 30/35. You can read data from heat cost allocators E-ITN 30 and water meter radio modules E-RM 30 from much bigger distance with panel antenna than using standard omnidirectional rod antenna. In most cases, data can be read without entering the building.
