Ultrasonic flowmeter can be divided into jacketed and pipe section types. It is commonly used with digital signal processing technique, multiple-pulse technique and error correction technique to adapt to the environment and to enhance its reliability. At present, it has been widely applied in chemical, electricity, petroleum, metallurgy, and other fields.
Ultrasonic flowmeter consists of ultrasonic generator, ultrasonic receiver, electronic line, flow display, and cumulative system.
Technical parameters
Backlight liquid crystal can display instantaneous flow, cumulative flow, flow rate, time, heat and other data |
||
Signal output |
Current output: 4-20mA or 0-20mA, impedance is 0-1K, accuracy is 0.1% |
|
OCT output: positive, negative, net cumulative flows and heat accumulated pulse signal or frequency signal of instantaneous flow |
||
Relay: can enter nearly 20 kinds of source signals (such as no signal, reverse flow, etc.) |
||
Sound alarm: the buzzer can gives alarm according to the settings |
||
Signal input |
Can enter two current signals (such as temperature, pressure, liquid level and other signals), in order to achieve heat measurement or one computer uses |
|
Automatic memory of cumulative flow 64 days ago, 64 months ago and 5 years ago |
||
Automatic remember of 64 times of call, power-off time and flow, to reduce loss of flow |
||
Automatically record working condition and abnormal times of flow 64 days ago |
||
Data interface: factory configuration is RS-232, becomes RS-485 by matching RS-232/RS-485 convertors |
||
Batch (quantitative) controller is programmable |
||
Cable length |
Model: the shorter the SYV50-3-T is better to reduce interference, can also be lengthened to 300 meters |
|
