1. Method of flowmeter reading
The method of flowmeter reading varies depending on the type of base height, with a focus on identifying the display area and mastering the numerical calculation logic. 1. The main feature of mechanical water meters is the combination structure of pointers and numbers. The reading is divided into two steps: • Integer part: directly read the black number in the center of the dial, in cubic meters. • Decimal part: Observe the surrounding red pointers. If the pointer marked with "× 0.1" points to 5, then the decimal part is 0.5 cubic meters. The total water volume is the sum of integers and decimals, for example, the black number displays 12 and the red pointer adds up to 0.5, resulting in a total usage of 12.5 cubic meters. 2. The electromagnetic flowmeter displays data directly through the display screen, and two parameters need to be considered: • Instantaneous flow rate: reflects the current flow rate, measured in liters per minute or cubic meters per hour. Accumulated flow: Record the total flow value of the device since its activation, usually in cubic meters or liters. Jian Xiang 3 The reading of vortex flowmeter is similar to that of electromagnetic flowmeter, and the key is to identify the display panel mode: some devices switch between displaying instantaneous flow and cumulative flow through buttons. -If equipped with a temperature sensor, pay attention to whether the data interface has mixed temperature parameters. four Ultrasonic flowmeter adopts non-contact measurement, and when reading, it is necessary to ensure that the probe is firmly installed and check the instantaneous flow rate and cumulative total amount of the host. -Regularly verify the calibration status of
2. What is the difference between integrated and split electromagnetic flow meters?
1、 Integrated electromagnetic flowmeter: Under good on-site and environmental conditions, an integrated type is generally selected, which means that the sensor and converter are assembled into one.
2、 Split type electromagnetic flowmeter: The sensor and converter are installed separately in different locations, and the split type is generally selected when the following situations occur.
(1) The ambient temperature or the radiation temperature on the surface of the flowmeter converter exceeds 60 ℃.
(2) In situations where pipeline vibration is significant.
(3) In situations where the aluminum front shell of the sensor is severely corroded.
(4) In places with high humidity or corrosive celery culture gases on site.
(5) Flow meters installed in high-altitude or underground environments where debugging is inconvenient
