Product Description
The P103 ultrasonic level meter is a compact measurement device including an electroacoustics converter, central processor unit and display module. Using the electroacoustics converter, the level meter transmits the sequence of ultrasonic pulses that spread towards the surface level. The converter recuperates reflected acoustic waves that are subsequently processed in
the electronic module. The intelligent evaluation block filters out interfering signals, compares the cleaned received signal with the false reflection map (e.g. from mixers, ladders, reinforcement etc.) and selects a suitable reflection (echo). Based on the period during which the individual pulses spread towards the surface level and back and based on the measured temperature in the tank, the instant distance to the surface level is calculated. According to the level height, the level meter output is set: :current 4 -20 mA with HART® protocol or output RS-485 Modbus and the measured value is displayed on the display.
The P103 is suited to measure the level of various liquid materials, sewerage waters, mash and paste materials, suspensions in closed or open vessels, sumps, reservoirs and open channels. In case the level of bulk solids is measured, the measurement range is reduced.
