The sewage ultrasonic level meter is a digital level meter controlled by microprocessor. In the measurement, pulsed ultrasonic waves are emitted by the sensor, reflected by the surface of the object and received by the same sensor, which converts them into an electrical signal. And by the time between the emission and reception of the sound wave to calculate the distance from the sensor to the measured object, is a non-contact, high reliability, cost-effective, easy to install and maintain the level measurement instrument. It does not have to contact the medium to meet most of the level measurement requirements, set the liquid level and water level ranging display and transmission functions in one, the measured medium is almost unlimited, can be widely used in a variety of liquid and solid material height measurement. At present, it is widely used in manholes, factory water tanks, tanks, municipal engineering, water, sewage treatment, water conservancy and hydropower, iron and steel, coal mines, electric power, petrochemical industry, urban rivers and lakes, transportation, and food processing and other industries.
Classification of Sewage Ultrasonic Level Meter:
Sewage Ultrasonic Level Meter is categorized into: one-piece type and split type. One-piece ultrasonic level meter adopts the principle of ultrasonic pulse for non-contact measurement, which is a non-contact, highly reliable, cost-effective, easy to install and maintain level measurement instrument; Split Ultrasonic Level Meter is to measure the time required for the whole process of an ultrasonic pulse from sending out to returning. Ultrasonic level meter is installed vertically on the surface of the liquid, it sends out an ultrasonic pulse to the liquid surface, after a period of time, the sensor of the ultrasonic level meter receives the signal reflected back from the liquid surface, the signal is selected and processed by the transmitter circuitry, according to the ultrasonic level meter sends out and receives ultrasonic waves of the time difference, the distance from the liquid surface to the sensor is calculated. Therefore, before we need to use the ultrasonic level meter in the sewage field, we need to confirm the field use of one-piece or split, due to site-specific conditions need to be different, on the one hand, we go to the scene whether it is convenient to the instrument side to watch, such as we installed in the higher tanks or through the rack in the center, then the one-piece may not be very convenient to watch the scene, on the other hand, is the installation of space! On the other hand, it is the installation space, sometimes it may be just a little bit short of the installation space, and need to put the meter head in another place.
Key Considerations for on-site Sewage Ultrasonic Level Meter Use?
- liquids/solids with foam;
- strong voltage, strong current and strong electromagnetic interference in the surrounding, try to avoid high voltage, high current and strong electromagnetic interference;
- strong wind and direct sunlight;
- strong vibration;
Ultrasonic Water Level Meter is a digital level meter controlled by microprocessor. In the measurement, pulsed ultrasonic waves are emitted by the sensor (transducer), reflected by the surface of the object and received by the same sensor, which converts them into an electrical signal. The distance from the transducer to the measured object is calculated from the time between the emission and reception of the sound wave. Due to the use of non-contact measurement, the measured medium is almost unlimited, can be widely used in a variety of liquid and solid material height measurement.
Advantages of Sewage Ultrasonic Level Meter
Due to the non-contact measurement, the measured medium is almost unlimited, which can be widely used for the measurement of the height of various liquids and solid materials. Ultrasonic level meter consists of three parts: ultrasonic transducer, processing unit and output unit. ultrasonic water level meter can use two-wire, three-wire or four-wire technology, two-wire system: power supply and signal output shared; three-wire system: power supply circuit and signal output circuit independently. The best measuring range of ultrasonic water level meter for ball tank is 0-50 meters. Secondly, it is suitable for a variety of working conditions, and can be applied to sewage treatment, manholes, factory tanks, tanks, municipal engineering, water supply, water conservancy and hydropower, iron and steel, coal mines, electric power, petrochemical industry, urban inland waterways and lakes, transportation, as well as food processing and other industries.
The advantages of Sewage Ultrasonic Level Meter are that there is no mechanical movable part, high reliability, easy and convenient installation, non-contact measurement, and it is not affected by the viscosity and density of the liquid. The disadvantage of Sewage Ultrasonic Level Meter is that the accuracy is relatively low, and the test is easy to have a blind spot. Can not measure pressure vessels, can not measure volatile media.
But because of the different occasions of the use of the ultrasonic water level meter, it is also made of different materials. Therefore, when asking about the ultrasonic level meter for sewage, you need to inform the use of the occasion and the measurement of the medium, as well as the height of the liquid level, etc., so that the business will determine the price according to the specific conditions.
