marine ultrasonic fuel level gauge and sender kit
Marine ultrasonic fuel level gauge and sender kit: Difference between level gauge and level transmitter: level gauge may not have 4-20mA transmission output, and level transmitter may not have on-site level indication. 1. The level of liquid medium in the container is called liquid level, and the instrument for measuring liquid level is called liquidometer. Level gauge is a kind of level instrument. The types of level gauge include tuning fork vibration type, magnetic levitation type, pressure type, ultrasonic wave, sonar wave, magnetic flap, radar, etc. 2. The liquid level transmitter is an extension and development of the pressure transmitter technology. According to the principle that the pressure generated by the liquid with different specific gravity at different heights is linear, the volume, liquid height and weight of water, fuel and paste can be accurately measured and transmitted.
The common liquid level sensors are photoelectric liquid level sensor, capacitive liquid level sensor and ultrasonic liquid level sensor. Photoelectric liquid level sensor is based on the principle of light refraction on two different media interfaces; The capacitive liquid level sensor has a built-in MCU chip, which uses algorithm control to determine whether the water tank is short of water by sensing the difference between the capacitance values when there is water and when there is no water; Ultrasonic liquid level sensor sends ultrasonic wave, which will reflect and form echo when encountering obstacles.
Marine ultrasonic fuel level gauge and sender kit: The fuel level transmitter is based on the principle that the pressure generated by the liquid with different specific gravity at different heights has a linear relationship to achieve accurate measurement and transmission of the volume, liquid height and weight of water and fuel. The common liquid level transmitters are input type liquid level transmitter, RF capacitive liquid level transmitter, etc. The input liquid level transmitter is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid; The principle of RF capacitance liquid level transmitter is that the metal inner core of the level detection line is the first level of capacitance, and the conductive liquid is the other level of capacitance, that is, the insulating outer layer of the level detection line acts as the medium between the two poles. With the change of the liquid level, the area of the liquid surrounding the level detection line changes accordingly.
