FilterSmart is an application-specific version of the EchoSmart™ ultrasonic interface level analyser. Implementations typically employ a sensor that includes a fully integrated scattered-light turbidity meter.
FilterSmart Sensor: The FilterSmart Sensor is a microprocessor-controlled piezoelectric transducer designed specifically for operation under water (submerged in the process liquid).
The Sensor generates an ultrasonic sound wave that propagates through the filter water above the filter media and is reflected back. The sound wave travels at known velocities, providing the ability to convert elapsed time into media level and expansion measurements. With a known dimension to the bottom of the expandable media, the measurement can be expressed in terms of the depth of the filter media, and the amount of expansion during backwash can be calculated both in engineering units and as a percent of the total media depth.
Sensors that include a scattered light turbidity measurement provide a highly useful additional measurement of backwash turbidity.
FilterSmart Controller: The FilterSmart Controller allows for programming and local monitoring of 1…16 FilterSmart Sensors. A single Controller can operate up to 16 FilterSmart Sensors in a wired or wireless field network. In either arrangement, the network is fully integrated and requires no software integration by the customer. The Controller handles all programming and monitoring functions for all sensors in the network.
FilterSmart Power Supply: The FilterSmart Power Supply unit provides power to a FilterSmart Sensor and acts as a communication hub to facilitate analog, digital and wireless RF communications from a FilterSmart Sensor.
The FilterSmart Controller and FilterSmart Power Supply unit are designed for indoor and outdoor installation.
APPLICATIONS
Drinking Water and Wastewater Treatment Filter
Tertiary Filters in Wastewater Treatment
Granular Media Pressure Filter
The FilterSmart backwash monitor is suitable for most municipal and industrial granular media gravity filters. It may also be used in granular media pressure filters subject to certain mechanical, pressure, physical and installation limitations.
