Ultrasonic Level Transmitters / Indicators are suitable for measuring the Level if fluid in the tank by non contcat method. The Transmitter works on Sound Waves and the out put from the same ( 4 to 20 mA) is given to a Digital level Indicator. The instrument is suitable for Foam Free and fumes Free material only. The type of Transmitters are 2 wire type and 3/4 wire type. The salient features and specifications are as follow: Simple push-button calibration (Accurate) Output 4-20 mA / 20-4 mA (Isolated on 4 Wire Model's only) Built-in temperature compensation Optional RS232 Or RS485 communications with calibration, diagnostics and data logging software PLC compatible Three or Four Wire Operation Self Cleaning operation of sensor face APPLICATIONS Solids (Models 25 U, 45U & 52U Below) Solids Range Approx. ½ of liquid C = Communication 4 for 485 or 2 for 232, Blank = no Communications XX = Operating Frequency, U = Ultrasonic 400 = AC Power, 300 = DC Power

1. J-Ultra series - A5/8/10A Ultrasonic Level Transmitter is professionally
manufactured, with various advantages of general-purpose ultrasonic
level Sensors, it realizes all-digital, user-friendly design, it also has
perfect material / liquid level measurement and control, data
transmission and exchange of human-machine functions. Main chips are
used dozens of pieces of imported industrial grade microcontroller,
digital temperature compensation and ultra-wide input voltage regulator.
It has good performance features such as strong anti-interference, reliability
of setting up upper and lower limit nodes, online output regulation, scene
display, analog option, switch and RS485 output, convenient interface to
related facilities. It does not need to contact most of the industrial medium
level, it is able to meet the measurement requirements, so that to avoid the
pressure-type, capacitive, float-style traditional measurements’
inconvenience such as plug, leakage, corrosion medium and difficult
maintenance.
