Ammonium carbonate flowmeter

Introduction: the ammonium carbonate flowmeter consists of two parts: sensor and converter Its principle is based on Faraday's electromagnetic induction law What are the precautions for the use of the ammonium carbonate flowmeter? Let's take a look at it with a small compilation Generally, the flow rate of the medium measured by the industrial electromagnetic flowmeter should be 2-4m / S in special cases, the minimum flow rate should not be less than 0.2m/s and the maximum flow rate should not be more than 8m / s If there are solid particles in the medium, the common flow rate should be less than 3m / s to prevent excessive friction between the lining and the electrode, what are the precautions for the use of the ammonium carbonate flowmeter? Let's learn about it with the small safety net of Baibai 1 The accuracy grade and function shall be selected according to the measurement requirements and use occasions, so as to achieve economic calculation For example, when it is used for trade settlement, product handover and energy measurement, the accuracy level should be higher, such as 1.0, 0.5 or higher; when it is used for process control, different accuracy levels should be selected according to the control requirements; Some are just to detect the process flow, without the need for precise control and measurement occasions, you can choose a slightly lower accuracy level, such as level 1.5, level 2.5, or even level 4.0, 2 When measuring medium flow rate, measuring range and caliber, the full flow rate of flowmeter can be selected in the range of 0.5-12m / s of measuring medium flow rate, with a wide range The specification (caliber) of the selected instrument is not necessarily the same as that of the process pipeline, which shall be determined according to whether the flow measurement range is within the flow rate range That is to say, when the flow rate of the pipeline is too low to meet the requirements of the flow instrument or the measurement accuracy cannot be guaranteed at this flow rate, it is necessary to reduce the diameter of the instrument, so as to improve the flow rate in the pipeline and obtain satisfactory measurement results 3 Try to avoid ferromagnetic objects and equipment with strong electromagnetic field, so as to avoid the magnetic field affecting the working magnetic field and flow signal of the sensor 4 There shall be sufficient space around the flowmeter for easy detection and maintenance The above is the introduction of the precautions for the use of ammonium carbonate flowmeter If you need to know more about industrial naphthalene and other small knowledge, please continue to pay attention to the food safety common sense column of Baibai safety net Editor in charge: Wang Xiaoli
