1. Flow meters that can measure the flow rate of bar type measuring tanks: There are three types of flow meters that can be used to measure the flow rate of bar type measuring tanks: ultrasonic flow meters, electromagnetic flow meters, and open channel flow meters Working principle: Using the time difference between the propagation of ultrasonic waves in the fluid, the flow rate is measured and the flow rate is calculated. 2. Installation characteristics: No need to damage the channel structure, non-contact installation can be achieved. 3. Applicable scenarios: It can adapt to various types of water quality in the bar type measuring tank, including clean water, sewage, etc. 4. Advantages: High measurement accuracy, not affected by factors such as fluid conductivity and density.
2. Electromagnetic flowmeter 1 Working principle: Based on the principle of electromagnetic induction, the flow rate is calculated by measuring the induced electromotive force generated when a conductive liquid flows. 2. Applicable scenarios: Suitable for measuring liquids with certain conductivity, widely used in the measurement of sewage flow in bar type measuring tanks. 3. Advantages: High measurement accuracy, good linearity, and small pressure loss.
III. Open channel flowmeter 1 Working principle: Combining the characteristics of the bar type metering tank, flow measurement is completed through liquid level measurement and a dedicated flow calculation model. 2. Applicable scenarios: Widely adaptable to open channel flow measurement scenarios such as drainage and irrigation where the bar type metering tank is located. 3. Advantages: It can adapt to different channel shapes and water flow conditions, with low installation and
2. What is the name of a flow meter with an impulse pipe?
Flow meters with impulse pipes mainly include differential pressure flow meters and Annubar flow meters.
. 1. Differential pressure flowmeter is based on the principle of fluid throttling, which guides the pressure difference before and after the throttling device (such as orifice plate, nozzle) to the differential pressure transmitter through the pressure pipe to calculate the flow rate. The application fields are mostly found in the measurement of liquid, gas, and steam flow in industries such as petroleum, chemical, and power. It is suitable for scenarios with stable working conditions and clean media.2. The Annubar flowmeter (flute shaped averaging tube flowmeter) uses a detection rod to capture the total pressure and static pressure of the fluid, and then transmits it to the transformer through a pressure pipe to calculate the flow rate.
. Its advantage lies in the measurement of large diameter pipelines, such as air pipelines and steam conveying pipelines in factories, which are suitable for high flow monitoring of gases, steam, or liquids.3. Calculation formula related to Biota flowmeter
