Online Crude Oil Moisture Detector Crude Oil Water Monitor Model: YYHS-1
1. Overview YYHS-1 crude oil water monitor (hereinafter referred to as the instrument) is a precision instrument for measuring the moisture content of crude oil. It is mainly used in the petrochemical industry to monitor the moisture content of crude oil online and also to measure the crude oil interface. The instrument adopts the upper computer debugging, display, remote control with the sampling style design; wide measurement range (full scale), high accuracy, can adapt to different site conditions; environmental protection, energy saving, safety, stable performance, good tracking. Instrument performance and design are at the leading level of similar products, and it is the first choice for crude oil monitoring.
2. Technical Features of YYHS-1 Crude Oil Water Monitor 2.1 Environmental Protection No Radiation 2.2 Simple structure: The sensor display is integrated, and it can display on the spot, and can also realize data transmission. Remote transmission mode: 4-20mA, RS485;
2.3 Convenient operation: The on-site adjustment and regular adjustment of the instrument are realized with the desktop water conditioning commissioning assistant, and no need to open the cover.
2.4 High temperature resistance: All components, integrated circuits and functional modules are of wide or extra-wide temperature class, which greatly improves the adaptability of the ambient temperature.
2.5 Automatic detection of oil-water mixing status LED indication: The “oil-in-water†and “water-in-oil†two different states exist in any oil-water mixed medium, which results in the measurement of duality, which will bring about the measurement. Great error. Automatic detection of these two states is of great significance for measurement accuracy.
2.6 temperature drift automatic correction: The instrument uses temperature measurement, the temperature drift curve to be placed in it, to achieve automatic temperature drift correction.
2.7 Good corrosion resistance, stable and reliable performance: The materials used are stainless steels with good corrosion resistance; components with high performance are used; all sensors of the sensor are sealed and cured; long-term temperature cycling test ensures that the instrument can be stable for a long time. work.
2.8 Use safety: The whole machine adopts the standard intrinsically safe energy limiter to completely isolate the safe area and the dangerous area, thus ensuring the safety requirements under the special use environment.
2.9 Good tracking: The sampling speed is fast, and it can truly reflect the change of moisture content of the tested medium.
2.10 Beautiful appearance: The sensing part is closely integrated with the display part, making the entire structure of the machine seamless.
3. Main functions of YYHS-1 Crude Oil Water Monitor The instrument is automatically powered on to indicate the moisture content. Indicates that the parameter is a real-time value. The input of all parameters and the realization of each function are coordinated by the upper computer water meter commissioning assistant and remote controller.

5. Basic principle of YYHS-1 Crude Oil Water Monitor This instrument uses the resonant state of high-frequency electromagnetic waves to measure the moisture content of crude oil.
The crystal oscillator circuit generates a constant frequency high-frequency electromagnetic wave and enters the resonant circuit. When the antenna is placed in pure water, the resonant circuit is in a squeezing state and the voltage value after the detection is high; when the antenna is placed in water-free oil The loop is detuned and the voltage after detection is low; when the antenna is placed in an oil containing a certain amount of moisture, the loop is in an intermediate state that is neither completely resonant nor fully detuned, and the detected voltage value is also in the above two. between. Therefore, measuring the voltage after detection can determine the moisture content at the antenna.
