1. Can gold be found by disassembling the AF-E400 flowmeter?

Disassembling the AF-E400 flowmeter is likely to result in no gold being found. The AF-E400 flowmeter belongs to industrial flow measurement equipment, and commonly used industrial materials such as plastic casing, metal fittings, and electronic components are commonly used in conventional manufacturing. Gold, as a high cost precious gold pure component, is generally not used in the production process of ordinary industrial flow meters. Only a very small number of customized equipment with special material functional requirements may use gold related components. Such scenarios are extremely rare.

2. What are the specifications and models of the flowmeter?

There are several models available: SG-NZ-KD

1, EXQ41W, ZXLDG, ZXGY.. A flowmeter is an instrument that indicates the measured flow rate and/or the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure fluid flow in pipelines or open channels. Flow meters are divided into differential pressure flow meters, rotor flow meters, throttling flow meters, narrow slit flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, etc. Classified by medium: liquid flowmeter and gas flowmeter. Flow meter selection: Five aspects can be considered, including flow meter instrument performance, fluid characteristics, installation conditions, environmental conditions, and economic factors. The detailed factors in five aspects are as follows:

1. Instrument performance: accuracy, repeatability, linearity, range, flow range, signal output characteristics, response time, pressure loss, etc;

2、 In terms o

3、 In terms of installation conditions: pipeline layout direction, flow direction, length of straight pipe sections on the upstream and downstream sides of the detection component, pipeline diameter, maintenance space, power supply, grounding, auxiliary equipment (filters, dampers), installation, etc;

4、 In terms of environmental conditions: temperature, humidity, electromagnetic interference, safety, explosion prevention, pipeline vibration, etc;

5、 In terms of economic factors: instrument purchase cost, installation cost, operation cost, calibration cost, maintenance cost, instrument service life, spare parts, etc.

3. How to calibrate a flowmeter? In practical use, if the temperature, pressure, and properties of the medium are different from the calibration time, or if the flow meter wears out significantly after long-term use, or if a non-standard flow meter is manufactured by oneself, it is necessary to calibrate the flow meter and re determine its flow coefficient or calibration curve. The calibration methods for flow meters include volume method, weighing method, standard flowmeter method, etc. Each flowmeter undergoes strict calibration and testing before leaving the factory. However, due to changes in the environment and differences in installation conditions during use, especially in the potato mold conditions where the measured medium is significantly different from the original calibration medium, the flowmeter may have corresponding indication errors d
