Open Channel Ultrasonic Flow Meter

Open Channel Ultrasonic Flow Meter Exclusive sensor for Open Channel flow High accuracy, high stability Downloading logging data by USB Data logging for long period simple structure Open channel ultrasonic is a flow measurement device best suited for storage tanks and open channels flow. It has a local display with buttons for quick and easy commissioning Temperature compensation is integrated and can be equipped with an external sensor for dynamic temperatrue compensation. The automatic false eacho detection toghther with easy set up makes it reliable and trustworthy. The measured level value is converted into the rate of flow in specific weirs therefore the accurate level value is very important. The measured flow information saves in memoery which can be downloaded by USB or transmitted by the digital communication such RS 485 or Modbus, the built EEPORM digital memory makes sure that the data will not lost in case of power failure Measurement Method : Ultrasonic Non-Contacting Cumulative Flow : 99999999m3 Display LCD displays the instantaneous flow and cumulative Flow Ambient Temp. : -30A C ~ +70A C Blind area i 0.25ma 0.5m Distance precision i 0.3%i standard condi Distance resolution 1 MM Flow precision i 1%a 5%i subject to the type of weir platei Pressure i Less than 4 atmosphere pressure Analog output i 4a 20mA Digital output i RS485 Modbus agreement or customized agreement Power voltage i DC24V/AC220Vi built-in lightning proof device Ambient IP Protection : IP 65 Salient Features: With the die casting aluminum alloy waterproof and Fire-proof shell, be Fire-proof and safe. For the circuit design, high-quality power modules are selected from the power supply and highly stable and reliably imported devices are used as its components. It can fully replace imported foreign meters of the same type. Patent sonic-wave intelligent technology software can make intelligent zed echo analysis. It needs neither debugging nor other special steps. This technology has functions of dynamic thinking and dynamican alysis.Our sonic-wave intelligent patent technology improves the precision (up to 0.3%) greatly. It can resist various interference waves. This product is a kind of non-contact instrument. As it doesna t contact the liquid directly, the failure rate is low. This product is designed with different installation methods. The user can make calibration independently as described in the manual All incoming and outgoing lines have lightning proof and short-circuit proof functions.
