Product Description UF2000B DN32-DN1000mm 4-20mA ultrasonic flow meter for waterProduct DescriptionIntroduction of UF2000B 4-20mA water flow meter clamp onUF2000B 220V AC 4-20mA ultrasonic water flow meter clamp on is designed to be installed in a fixed location for long-term flow measurement. Ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-fouling operation and easy installation. Transit-time flow meter utilizes two transducers that function as both ultrasonic transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from each other. The transducers can be mounted in V-method where the sound transverses the pipe twice, or W-method where the sound transverses the pipe four times, or in Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This selection of the mounting method depends on pipe and liquid characteristics. The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pipe.Specs of UF2000B 4-20mA ultrasonic water flow meter clamp onProducts nameUF2000B 220V AC 4-20mA ultrasonic water flow meter clamp onMain unitAccuracyBetter than ±1%RepeatabilityBetter than 0.2%PrincipleTransit-time measuring principleMeasurementPeriod500msDisplayLCD with backlight, display accumulated flow/heat, instantaneous flow/heat, velocity, time etc.OutputAnalogue output: 4-20mA or 0-20mA current output.
