BBZ-pipeline Ultrasonic Flowmeter
Brief description:
BBZ-pipeline ultrasonic flowmeter measures the liquid flow rate within the round tube based on the ultrasonic transit-time principle, compact and rugged structure, high precision, 4 ~ 20mA or 0 ~ 20m output, with RS-232 or RS-485 communication.OTC output positive , negative and the net cumulative flow rate or instantaneous flow rate frequency signal, a voice alarm function, it can automatically remember the cumulative flow of the first 64 days, 64 months or the first five years .5 analog current signal, Chinese LCD to display positive , negative and the net cumulative flow rate or instantaneous flow rate ,velocity, time, analog input and other data, the relay can output nearly 20 kinds of source signals. Using industrial grade electronic components, relying on battery power, no mechanical rotation, no wear, no pressure loss, BBZ-pipeline ultrasonic flowmeter is an all-electronic industrial water meter. With high accuracy, good reliability, low cost, long term life, the product can completely replace other types of water meters.
