Water Tower Temperature Control
Monitor and control water temperature in a fresh water supply tower to prevent freezing in cold regions.
Application Overview
Much of our water supply system uses above ground water supply tanks that are vulnerable to a number of environmental threats. One of them is cold weather. While it's technically possible to put water supply tanks underground to keep it safer, doing so is incredibly expensive and requires massive civil engineering projects, many more pumps, and a lot more energy consumption.
In reality, it's easier to simply add heat and insulation to vulnerable points in our water supply as needed.
A common point of concern in the system is the riser, a pipe which runs from ground level up to the bottom of the water supply tank. These pipes are small enough that they're vulnerable to freezing rather quickly. Malcolm Jackson, the Business Development Manager for tank and maintenance supply company Utility Service Co., Inc., explains:
"Many tank risers are wrapped with heat tape, covered with insulation and capped by an aluminum jacket. In addition, a heating system may be installed in an adjacent building or into the valve pit underneath the riser. The heater introduces heated water or steam into the base of the riser. In either case, the heat rises into the tank to [mitigate] freezing."
This is only one example of preventing water infrastructure from succumbing to the cold, and there are countless other industrial use cases for water temperature control; from food processing to data centers. Whether it's meant for consumption or for processing, water management is incredibly important.
Common Water Heating Problems
Environmental Factors
Extreme weather conditions increase the freeze threat and can cause temperatures to drop suddenly.
Connectivity Failure
Monitoring and control logic in remote locations can fail if network connectivity issues arise.
High Energy Consumption
Water temperature maintenance uses a lot of energy and can become very expensive.

Case Study: Rural Northeast Municipality
A municipal customer in the Northeast US heats the riser on their water supply tank with a 1-million BTU heater. In order to prevent sudden freezing, they needed a controller that could take into account weather data like temperature and wind speed. However, it needed to intelligently react to dropping temperatures to conserve energy.
The solution was our X-410 controller with 4 digital inputs, 4 relays, and up to 16 1-Wire temperature sensors. The X-410 is a capable stand-alone controller which supports all the sensors and custom control logic needed. Our customer used two temp sensors connected to the X-410’s 1-Wire Bus to monitor the water riser temperature and the outside air temperature, along with monitoring the frequency of a contact closure inside an anemometer (wind speed sensor).
Custom control scripts were then written to consider both temperature and wind speed to run the heater at timed intervals to prevent freezing, and then to run continuously as the temperature drops low enough. This gradual response avoids excessive energy consumption, while staying ahead of extreme weather conditions.

Frequently Asked Questions
Answer
For a simple water tank temperature monitoring and control, similar to our customer above, 2 temperature sensors, one measuring the water riser and one measuring outside air, are sufficient and can be monitored with a single ControlByWeb I/O device. Our maximum number of temperature sensors on our X-410 I/O device is 16 - more than enough capacity.
Answer
You can designate one of our X-410 units as a master controller to pull in data from our other remote I/O devices and temperature sensors. Once a remote device is added, the I/O on that remote device becomes available as if it was directly connected to the master X-410. You can then setup the temperature sensors and heaters and create custom logic ... all on one centralized interface!
Answer
Our 400-Series controllers can be programmed using our intuitive, no-code Task Builder software which is built into the devices. You can also write BASIC scripts for more advanced logic.

Answer
Many of our controllers can monitor a variety of environmental sensors. Most control logic is based on individual sensors for maximum versatility. Our controllers have both analog and digital inputs to capture nearly any sensors data. Our X-4XX series controllers have digital inputs with frequency and counting capabilities for specific types of weather sensors. For example, some wind sensors have a contact-closure frequency output that is based on the number of on/off pulses in a second. Rain gauges also use contact-closures to measure rainfall. The frequency and counting features on the X-4XX series controllers accommodates these outputs.
Answer
Yes. Many of our controllers support periodic logging intervals of sensor data, including temperature data. We store a log file on board which can be accessed via a web browser, sent as an email, or uploaded to an FTP server. Sensor data is also available via Modbus TCP/IP to interface with existing SCADA or other control systems.
