German SUNGRIM sensor SUNGRIM model SUNGRIM price

SUNGRIM sensor is a sensor that measures the air flow drawn into the engine. In electronically controlled gasoline injection engines, to achieve the optimal mixture concentration under various operating conditions, it is essential to accurately measure the amount of air drawn into the engine at every instant, using this as the primary basis for the ECU to calculate (control) the fuel injection quantity. If the air flow sensor or its wiring fails, the ECU will not receive the correct intake air signal, preventing normal control of fuel injection, which will result in a mixture that is too rich or too lean, causing abnormal engine operation.

SUNGRIM sensor features

Currently, baffles can be designed according to the water flow rate to reduce the water resistance generated when water flows through the flow sensor, thereby reducing head loss in the water system. However, due to long-term impact from water flow, baffle-type sensors still suffer from fatigue issues; even if the flow value is calibrated at the factory, setpoint drift may occur. They are typically used in applications where precise protection of flow values is not required, i.e., for flow interruption protection in case of sudden stoppage of water flow in pipes. There are very few designs specifically for water-source heat pump units in China. The baffle type is specifically developed for water flow monitoring in water-loop/ground-source heat pump air conditioning units. It is equipped with different baffles for different pipe diameters, and the water resistance of each baffle does not exceed 0.5 meters of water column, which is significantly lower than that of target-type sensors. Each baffle-type flow sensor is equipped with pipe fittings identical to those of the water-loop heat pump unit's water pipes. Only connection to the water pipe is required on-site, without any modification to the baffle. Additionally, the pressure rating of the baffle-type flow switch is greater than 25bar, making it a low-cost flow switch for water-loop heat pump units with less stringent water flow requirements. Feedback from use in water-loop/ground-source heat pump units indicates that differential pressure switches can effectively identify problems in the on-site installation of water piping for water-loop heat pump units, completely avoiding heat exchanger freeze-up caused by low water flow. Flow sensors can also protect against heat exchanger freeze-up when water flow decreases due to clogged water filters. Furthermore, water pipe differential pressure switches do not carry the risk of fatigue failure associated with target flow switches. Especially when there is a small amount of air in the water piping, the flow sensor operates very stably, without floating issues similar to those of target flow switches. Feedback from years of use has not revealed any failures of the differential pressure switch itself.

SUNGRIM sensor principle

Basic principles and types of ultrasonic flowmeters: When ultrasound propagates through a flowing fluid, it carries information about the fluid's flow velocity. Therefore, the fluid's flow velocity can be detected by receiving the ultrasound, and thus converted into flow rate. Depending on the detection method, ultrasonic flowmeters can be classified into different types such as transit-time difference method, Doppler method, beam deflection method, noise method, and correlation method. Ultrasonic flowmeters are non-contact instruments that have only begun to be applied in the last decade or so with the rapid development of integrated circuit technology. They are suitable for measuring fluids that are difficult to contact and observe, as well as large-diameter pipe flows. When linked with a level gauge, they can measure the flow of open water channels. Using ultrasonic flow measurement means no measuring elements need to be installed in the fluid, so the fluid's flow state is not altered, no additional resistance is generated, and instrument installation and maintenance do not affect the operation of production pipelines, making it an ideal energy-saving flowmeter. Industrial flow measurement commonly faces difficulties in measuring large pipe diameters and high flow rates. This is because general flowmeters encounter manufacturing and transportation difficulties as the measurement pipe diameter increases, leading to higher costs, greater energy loss, and installation challenges. Ultrasonic flowmeters avoid all these disadvantages. Since various types of ultrasonic flowmeters can be installed externally on the pipe for non-contact flow measurement, the instrument cost is basically independent of the measured pipe diameter. In contrast, the cost of other types of flowmeters increases substantially with diameter. Therefore, the larger the diameter, the more superior the cost-performance ratio of ultrasonic flowmeters compared to other types with similar functions. They are considered excellent instruments for large-diameter flow measurement. Doppler method ultrasonic flowmeters can measure the flow of two-phase media, so they can be used for measuring dirty flows such as sewers and sewage. In power plants.

SUNGRIM sensor selection

When selecting a flow sensor, users should choose the appropriate sensor based on their own needs. Many users have different requirements for the sensors they use, so the standards they select also vary. If highly professional data and results are needed, national standards should be selected. However, if it is just for a simple instrument within an enterprise for rough analysis, enterprise standards can be selected. If you intend to purchase a flow sensor, please consider carefully and choose sensors with guaranteed quality and good usability. Many people assume that new sensors have higher technology, which is a very one-sided view. New products must possess mature technology to be considered good products. In many economic sectors, accurate flow measurement has become extremely important. Nowadays, sensors are basically used to measure flow quantities. Sensors sense fluid flow and convert it into usable output signals; installing sensors makes operation simpler and more convenient. The quantity of flowing objects passing through per unit time is called flow rate, and different flow sensors are used for different objects, often distinguished by the measured medium and the measurement method. Flow sensors are generally used for the flow of media fluids in industrial pipelines. Under normal circumstances, there are various media such as gases, liquids, and steam, and several types of flow sensors can be universally used for these media. The first type is the vortex flow sensor. Another type is the ultrasonic flow sensor. With the development of ultrasonic technology, ultrasonic flow sensors can generally measure the flow of most flowing objects. Ultrasonic flow sensors also have various measurement methods, each with its own characteristics. We should select based on factors such as the properties of the measured fluid, flow velocity distribution, pipeline installation location, and accuracy requirements. Since industrial flow measurement commonly faces difficulties in measuring large pipe diameters and high flow rates—because general flow sensors encounter manufacturing and transportation difficulties as the measurement pipe diameter increases, leading to higher costs, greater energy loss, and installation challenges—ultrasonic flowmeters avoid all these disadvantages. The flow measurement accuracy of ultrasonic flow sensors is hardly affected by parameters such as the temperature, pressure, viscosity, and density of the measured fluid. They can also be made into non-contact and portable measuring instruments, thus solving flow measurement problems for strongly corrosive, non-conductive, radioactive, and flammable/explosive media that are difficult to measure with other types of instruments.
