Ultrasonic flow transmitter

详情

Low cost ultrasonic flow meter is the latest innovation from Teren, It employs cutting-edge technologies on ultrasonic transit-time measurement, digital signal processing and surface mounting electronics. It provides abundant capabilities for accurate liquid flow measurement from outside of a pipe. The proprietary signal quality tracking and self-adapting techniques allow the system to optimally adapt to different pipe materials automatically Low cost ultrasonic flow meter can be equipped with an optional LCD display /key board module. The users can either users can either use the RS***5 interface or the display /keyboard interface to program the flow meter. The transducer installation is also simple and no special skills or tools are required. Due to the non-intrusive nature of the clamp-on technology, there is no pressure drop, no moving parts, no leaks, no risk of contamination, no risk of corrosion, no pressure dependency. Low cost ultrasonic flow meter is designed for large quantity, low cost applications. Its unique features, particularly very low cost , very high performance and very small size , make it the ideal choice for industrial automation, processing control, water source management, flow meter networking and OEM applications Accuracy Better than Ã�±1% for velocity above 0.6ft/s Repeatability Better than 0.2% Response Time 0.5s Velocity ***2m/s Display /Keyboard Optional. LCD with backlight. 2Ã�?*0 letters. Display instantaneous flow rate, accumulated flow rate (positive, negative and net rates), velocity, time, analog inputs, ect. Signal Input Current input: ***0mA., 0.1% accuracy. Can be used for signals such as temperature, pressure, liquid level, ect. Signal Output Current output: ***0m A . Impedance **1k, Accuracy 0.1% OCT output: two channels. Can be programmed as pulse signal for accumulated flow rate (positive, negative and net rates); frequency signal for instantaneous flow rate; ON/OFF signal for relay drive or alarm drive; batch control Communication Interface RS***2 and RS***5 (note: can not be activated simultaneously) Recording Automatically record the following information: l The totalizer data of the last *4 days/*4 months; l The time and corresponding flow rate of the last *4 times of power on and off events. Allow manual or automatic flow loss compensation l The instrument working status of the last **8 days Powder *2VDC~*4VDC Can be customized to *2VDC or 5VDC Liquid Types Virtually all commonly used liquids (full pipe) Liquid Temp 0â??~**0â??
