1. How to read a diesel flowmeter? The reading methods of a diesel flowmeter are mainly divided into three categories: pointer type, digital type, and mechanical/intelligent counter. It needs to be read in combination with the display type and operating specifications, and the key is to confirm the unit, range, and display mode.
1. Reading of pointer flowmeter (commonly seen in metal tube floats, etc.) 1 Vertical line of sight reading: Ensure that the line of sight is perpendicular to the pointer and scale line to avoid visual errors
2. Confirm the scale units: common units are cubic meters per hour (m ³/h) and liters per minute (L/min), which need to be matched with actual needs
3. Range check: If the pointer exceeds the range (such as pointing outside the maximum value of the scale), it may be due to flow overload or equipment failure, and the machine needs to be stopped for inspection.
2. Digital flowmeter reading (mainly LCD display) 1 Switching display mode: Switch between instantaneous flow rate (unit time flow rate) and cumulative flow rate (total flow rate) through buttons or menus. Industrial scenarios require simultaneous attention to both
2. Check unit and accuracy: The display screen will indicate the unit (such as m ³, L) and accuracy (such as ± 0.5%), and confirm whether they meet the measurement requirements
3. Remote reading and counting (intelligent type): Some flow meters with communication functions can remotely obtain data through wired/wireless connections to a computer, and only the local display screen needs to be viewed on site.
III. Mechanical/Intelligent Counter Reading 1 Mechanical counter: directly reads the numbers displayed on the gear transmi
2. Intelligent counter: supports data export and analysis, and detailed parameters can be viewed on site through the display screen. At the same time, it can be connected to the monitoring system to achieve automatic recording.
IV. Precautions that affect the accuracy of readings 1 Temperature and pressure compensation: Changes in diesel temperature and pipeline pressure can affect volumetric flow rate, and it is necessary to confirm whether the flowmeter has automatic compensation function. 2. Regular calibration: It is necessary to calibrate periodically according to the equipment manual (such as once every half a year) to avoid errors caused by wear or drift.
2. What is an intelligent flowmeter and what are its uses?
Intelligent calendar flow meters include intelligent electromagnetic flow meters, intelligent vortex street flow meters, intelligent spiral vortex gas flow meters, metal tube float flow meters and other intelligent instruments.. Extended reading: Principle: The measurement principle of the intelligent limb state beam electromagnetic flowmeter is Faradays law of electromagnetic induction. The main components of the sensor are the measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing. Purpose: It is mainly used to measure the volumetric flow rate of conductive liquids and slurries in enclosed pipelines with trace carrying capacity. Including highly corrosive liquids such as acids, alkalis, salts, etc. Fields: Applied in industries such as petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking, as well as environmental protection, m
