Liquid level sensors come in many different shapes and sizes, and are made for a variety of applications.
For years mechanical floats have been the standard for maintaining the liquid level in an application. Over the years, these mechanical floats have evolved into electric switches that are more reliable and have more control of the application’s liquid level.
These electric switches basically come in 3 style types. These three sensor types have dominated the electric liquid level control market, but all four old style devices have unique issues that cause grief, annoyance, and in some cases, a hole in your wallet.
- Completely Modular, 15 year average life cycle
- Poor Water Quality is not an issue for Waterline Controls
- No mechanical parts except for relays to operate valves or pumps
- The sensor tips will not plate, foul, or deteriorate
- Lifetime Limited Warranty for all Waterline Control Parts
- There is a Press-to-Test switch for easy troubleshooting
Older “legacy” technologies are riddled with inherent problems, they have been the standard for liquid level control and water tank level sensors because there has been nothing better, or different enough, to justify a change. This fact laid the foundations for the new paradigm from Waterline Controls.Over the years we listened closely to the complaints of those who purchase, install, and maintain cooling towers, lift stations, sumps, and water holding tanks. By understanding the common issues of both mechanical floats and electric switch sensors, we designed and created completely new electronic switch sensor that runs on software and does not plate, foul, or deteriorate the sensor probes. This style of liquid control is based on simplicity and reliability.
Legacy Type Sensors
- This would include the old fashion style float switch, and modern reed switches.
- Capacitive Sensors
- These require manual calibration to be effective. The dialectic constant of the material can change over time, altering accuracy and requiring adjustments. Continue reading…
- Conductive Sensors
- Poor water quality can cause the probes to foul, deteriorate or pit, needing to be replaced after one to two years. “Throwaway Technology” with a short life cycle. Continue reading…
- Ultrasound Sensors
- Foaming or changes in the transitivity density, temperature or other characteristics of the medium can effect accuracy. Requires precise, and expensive, calibration. Continue reading…
