Ultrasonic Flow Meter (China)

? Relay: Nearly 20 kinds of output signals (if there is a signal, reverse flow, etc.) ? Voice Alarm: Buzzer alarm can be set to make sounds (such as flow excessive, too small, etc.) ? Signal input enter two-circuit current signal (such as: temperature, pressure, liquid level signal, etc.) in order to achieve heat measurements or one dual-purpose machine automatically memorize cumulative flow for the former 64 days, the former 64-month, and the former 5-year Automatically memorize the call, the time and power flow for former 64 times, can be manual or automatic fill volume Automatically memorize Whether the job status of flow is normal or not and times of abnormal status ? Data Interface: standard RS-232C or RS-485 (compatible with other domestic manufacturers) Programmable bulk (quantitative) controller ? Pipe Steel, stainless steel, cast iron, copper, PVC, aluminum, glass steel, rigid metallic plastic etc, permit lined ? Straight pipe sections the best sensor installation point: the upper reaches = 10D, downstream = 5D,outlet = 30D away from the pump (D refers to pipe diameter) ? Measurement medium: water, sea water, industrial effluent, acid-base fluid, a variety of oils, and fluids can conduct sound waves ? Velocity range: 0 ~ ± 30m / s ? Measurement accuracy: better than ± 1%
