Ultrasonic level sensors (see Figure 8) measure the distance between the transducer and the surface, using the time required for an ultrasound pulse to travel from a transducer to the fluid surface ...

Some of the other level measurement methods are based on specific gravity, which is a physical property commonly used to sense the level surface. These devices consist of a simple float, whose ...

AEM (aem.eco), the essential source for environmental insights, today announced the acquisition of Van Essen Instruments, a renowned provider of precision groundwater and surface water monitoring ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

As the need for more — and more precise — data grows, traditional sensor technology still struggles to collect sub-surface level information, says Chuck Fralick, vice president and chief ...

Researchers have developed a method that allows the water level of rivers to be monitored around the clock. The cost-effective sensor is for instance suitable for area-wide flood warning systems.

The cost of the new water level sensors is nearly $26,000. A third-party company is set to handle installation, engineering, and an online database.
