flowmeter

1. Overview of Flow Meter

The English name of a flow meter is flowmeter, which is defined by the National Science and Technology Terminology Review Committee as 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. The commonly used unit in engineering is m3/h. It can be divided into instantaneous flow rate (Flow Rate) and cumulative flow rate (Total Flow). Instantaneous flow rate refers to the amount of effective cross-section that passes through a closed pipeline or open channel per unit time, and the substances flowing through can be gas, liquid, or solid; Accumulated flow refers to the cumulative amount of fluid flowing through the effective cross-section of a closed pipeline or open channel during a certain time interval (one day, one week, one month, one year). The cumulative flow rate can also be obtained by integrating the instantaneous flow rate with time, so the instantaneous flow meter and the cumulative flow meter can also be converted into each other.

2. How to adjust the Chuanyi flowmeter

Adjust it by pressing the compound button and confirmation button..

1、 Check the correct connection method of instruments on pipelines (including power lines) and the firmness of installation.

2、 Then ground the sensor part properly and ensure that the fluid in the pipeline is still when debugging the instrument zero point.

3、 After the power switch of the instrument is turned on, that is, after the instrument is powered on, it automatically enters the measurement state.

4、 In the measurement state, press the "composite key+confirm key" to display the converter function selection interface and adjust the Chuanyi flowmeter.

3. Characteristics and uses of various flow meters

4. What are the specifications and models of flow meters?

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 of fluid characteristics: temperature, pressure, density, viscosity, chemical corrosion, abrasiveness, scaling, phase mixing, phase change, conductivity, sound velocity, thermal conductivity, specific heat capacity, isentropic index;

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 (fi
