FloLevel Technologies acoustic density interface transmitter

FloLevel Technologies has launched a self-cleaning acoustic density interface transmitter for mining and applications that suffer from build-up issues. The technology accurately measures most liquid/slurry solutions where an interface of up to two densities exists that needs to be monitored continuously.

The level interface transmitter tracks liquid-to-liquid, liquid-to-paste and liquid-to-granular interfaces. It is a high-powered, ultrasonic, self-cleaning transmitter that is not affected by changes in the conductivity and dielectric of the solution. The pulse amplitude causes a phenomenon called rarefaction, which causes cavitation to be produced from the array transducer diaphragms as they pulse. The cavitation bubbles oscillate in front of the diaphragm, which causes implosions that generate high energy levels, removing scale and other build-up problems.

The system is easy to install from the top of the tank and is easy to calibrate. It comes with adjustable 316SS bracket, with flange mounting options and a colour display controller mounted in a stainless steel enclosure. It can measure the density interface, with a maximum control range of 6400 mm, and resolution accuracy options available are 15 and 25 mm. Various output capability options are available, eg, 3 x 4-20 mA, Modbus, ProfiBus, Foundation FieldBus, DeviceNet and Ethernet.

The product is suitable for all mineral slurry applications.
