Remote Telemetry Units for Water Applications
SDI-12 Sensor Connection and GPRS Data Transmission Lower CostsÂ
CHESTERLAND OH – At CAS DataLoggers we receive calls in spring and summer from customers working in the hydrologic or meteorological industry who need to measure rainfall and set flood warning alarms. This is a common application with municipal drainage authorities, environmental researchers and the EPA, all of whom seek to lower deployment costs and reduce site visits. Remote flood warning systems are an excellent value for these applications, providing many years of uninterrupted, reliable operation at any remote site even under the most hostile environmental conditions. Here we give a brief walkthrough of application challenges and how users can meet them using RTU data loggers.
SDI-12 rainfall alarm systems:
Isodaq remote telemetry units (RTUs) are low-cost monitoring and alarm solutions which give users valuable extra time to organize emergency response in advance of an approaching flood event. Using RTUs, emergency responders also have access to better information on flooding and where to concentrate their efforts.
Most rapid-response catchments are sensitive to high-intensity, localized storm rainfall over short durations. Isodaq early warning systems can be set to trigger an alarm when a critical intensity rate is exceeded, well before a flood level threshold in a watercourse is reached. In this event, these systems automatically forward SMS or Email messages to emergency staff.
Capture a photo of trash grill blockage status:
Flooding in urban areas is often caused by a buildup of debris at culvert grills. To combat this, an Isodaq RTU outstation can detect rising flood levels and can even deliver a Current Status picture to standby maintenance personnel. Benefits include:
•Â RTU loggers monitoring water level can trigger an observation camera
•Â The logger can automatically email photos to emergency staff
•Â High-level alarms automatically transmitted to users
•Â Helps prioritize sites where debris clearance is needed
Alert motorists of ford or road closures with LED road signs:
Isodaq water-level loggers can also activate a 'Road Closed' warning on an electronic LED road sign to improve road safety 24 hours a day, 7 days a week. These intelligent systems have several useful features:
• Activated by water level alarm
•Â High-visibility flashing LED display
•Â Helps stops motorists from driving into deep floodwaters
•Â Battery-operated without mains power
Rapid Low-Cost Deployment:
•Â Step 1—Select Gauge Type. Choose from automatic rain-gauges from quality suppliers such as Casella, EM or Sutron.
•Â Step 2—Fit GPRS Logger. Isodaq’s Tadpole R2 GPRS Logger is the ideal rainfall logger, having been designed to fit inside a rain gauge.
•Â Step 3—Collect data. The ISODAQ TimeView Telemetry website automatically collects data via GPRS and delivers graphs and alarm messages to your desktop PC or smartphone via an Internet connection.
Remote site data sent directly to your PC:
For quick access to local flooding information, Isodaq’s new FloodView website is a simple flood status page for keeping key staff or the public informed on current flooding status. The site uses clear graphics and is accessible from any PC, Tablet or smartphone with an internet connection. Accessible via Internet browser, the website shows:
•Â Latest flood status information to multiple recipients
•Â One-page graphics display with no training required to interpret
•Â Displays photos, flood level graphs and alarm status
Rainfall sensors for any application:
The Isodaq product family comprises the popular Frog RX GPRS datalogger which connects to a choice of water-level sensors from a variety of manufacturers. Installing a real-time rainfall logger gives users reliable and immediate flood level warning. Several factors reduce the cost of deployment:
•Â GPRS logger fits inside 100mm tube
•Â Low-impact, vandal-resistant installation
•Â Choice of water-level sensors for different channels
•Â Automatically transmits alarms as flood level rises—no visits needed
