The systems required a centralized office location to communicate wirelessly to remote monitoring stations and regulator control stations within the community. Radio modems were used for communicating real-time data to and from the central office to the remote stations. DGH was contacted to provide a hardware solution that would measure pressure sensors, control ...
Whether water is flowing into local homes or flowing out as wastewater to a treatment plant, the process requires a network of pipes, pumps, and other equipment. If there’s a problem in the system, the results can be devastating. Residential and commercial customers rely on a steady stream of clean water, and a blockage in wastewater management can create an environmental hazard. Employing ...
The data logger of the shore station receives data from the RDCP 600 and the WTR-9 via radio modem. An ATEX zone 1 cabinet at the Dolphine 8 contains the interconnection between the units via a Galvanic Isolator and a Cascade Coupler. ...
Data carrier is normally VHF/UHF radio telemetry with a transmitting range of up to 15km depending on the ground conditions. Radio telemetry can be replaced with GPRS on request. Incoming data is handled by AADI Geoview software and stored in a SQL database. ...
In addition, the computer is no longer a critical piece of system operation. PC-programmable radio modems (2-watt UHF, 9600 bit/sec) transmit data in a peer-to-peer network across the system. The configuration of the radio network is accomplished in ATSI SCADA RTUs. Operationally the SCADA system automatically controls and monitors the following ...

Data can be sent to a website via a General Packet Radio Service modem. The key to the SF6MFU's performance is an accurate mass flow controller to regulate the SF6 entering the vessels. Every SF6MFU includes a Sierra SmartTrak® 100 mass flow controller, a pressure transmitter, a battery monitor and guarding system, overshoot pressure protection, a data ...
The DOT Logger transmits sensor readings via radio to a nearby land line modem. From Mr. Vandehey’s computer with a phone modem, data is collected and processed using DAQFactory data management software. ...
Beyond WiFi, there are other wireless technologies like spread spectrum radio modems and proprietary wireless networks. These typically operate on either the 900 MHz or 2.4 GHz industrial, scientific and medical (ISM) frequency bands. For example, we used a half dozen radio modems to collect data from test wells spread around a ...

An easier and less expensive approach would be a pair of Ethernet radios connecting one of our Tank Cloud remote level transmitters to your router of choice. ...
The DT80’s extensive communications capabilities include 2 RS232 ports with modem support, USB, Ethernet and USB memory stick ports so users could connect to the datalogger locally, remotely or over the Internet. ...
Measurement data is transmitted wirelessly through GSM modems or closed UHF radio systems. Teletronic's service includes rental, sales, installation and operation of complete monitoring systems. ...
The SediLink radio modem can be mounted directly on a SediMeter SM3A for lab use. ...
The units contain survey grade NovAtel receiver boards, VHF Radio Modems and Bluetooth capability. For even greater positional precision, the (GNSS) receivers can connect to the Algiz 10X via Bluetooth for decimetre accuracy. ...
The authorities of Wroclaw reorganized security and crisis management division and built a local communication system for authorities, police, ambulance service, city guards and fire brigades based on TETRA trunking radio. Task Build and erect a monitoring system for water level and water temperature, solar powered with communication via existing TETRA radio ...
Radio communications is a growing, cost-effective solution for environmental monitoring applications. The International Telecommunication Union (ITU) governs the allocation of communications frequencies world-wide, with participation by each nation’s communications authority (The Federal Communications Commission (FCC) in the United States).Radio ...
