In this paper there is a scan orientation system based on ultrasonic level sensor and stepper motor. 本文详细介绍了一种结合超声波传感器和步进电机的扫描定位系统,分析了扫描定位原理,引入了温度补偿提高测量精度。
So, it should be a developing trend to replace the target type flow sensor with the ultrasonic level sensor to measure drilling fluid flow out rate. 因此,应用超声波液位传感器(USLS)取代靶式流量传感器进行钻井液出口流量的检测应是一种发展趋势。
During drilling, in order to realize drilling fluid flow out rate monitoring, the two different detection methods of the target-type flow sensor and ultrasonic level sensor were often used in comprehensive mud logging to measure drilling fluid out rate. 钻井过程中,为了实现对钻井液出口流量的监控,综合录井常使用靶式流量传感器或超声波液位传感器(USLS)测量钻井液出口流量变化。
The sensors including oil pressure sensor, proximity switch, flow sensor, pullon the rope sensors, current sensors, gas concentration sensor, power transducer, ultrasonic liquid level sensor, temperature sensor, tension sensor. 传感器有油压传感器、接近开关传感器、流量传感器、拉绳传感器、电流传感器、气体浓度传感器、功率变送器、超声波液位传感器(USLS)、温度传感器、拉力传感器。
When using ultrasonic to observe a liquid level from outside of the tank, the ultrasonic sensor is often fixed on the bottom of a liquid tank. In such case, the size of the blind zone directly influences the observation of a raffinate. 利用超声波从液罐外部观测封闭罐中的液位时,由于超声波传感器被安装在液罐的底部,盲区的大小直接影响残液的测量。
