1. What are the applicable working conditions for a V-cone flowmeter with a length of 700?
The applicable working conditions for a 700mm caliber V-cone flowmeter can be divided into two categories: general industrial working conditions and special working conditions. The core is to adapt to fluid measurement scenarios with high flow rate, high viscosity, and multiple impurities Universal family standard operating conditions - Measurement medium is clean liquid: such as clean water, thermal oil, softened water and other low impurity single-phase fluids, suitable for temperature range of -40 ℃~400 ℃, pressure up to 42MPa - Measurement of clean gas: including compressed air, natural gas, nitrogen and other gas media without particulate impurities - Measurement of saturated/superheated steam: steam operating conditions in accordance with GB/T 21446 standard, suitable for high flow rate steam measurement 2 Special adaptation conditions - High viscosity fluids: such as crude oil, asphalt, heavy oil and other media with a kinematic viscosity of up to 10000mPa · s, the V-cone cone cone structure can reduce fluid wall hanging and sedimentation - Impurity containing fluids: Sewage, mud, coal powder conveying fluids containing a small amount of solid particles (≤ 10% volume ratio), as well as industrial wastewater with a small amount of oil pollution - Large pipe diameter and wide range working bucket conditions: 700mm diameter, suitable for industrial main pipelines with an inner diameter of 650-750mm, with a range ratio of up to 10:1, can cover extremely low flow rates (minimum 0.1m/s) to ultra-high flow rates (maximum 10m/s for liquids and 100m/s for gases) scenarios - High temperature and high pressure conditions: Su
2. Reading of liquid flow meter
The reading method of liquid flow meter mainly depends on its type, and the core is to distinguish between instantaneous flow and cumulative flow, and correctly set medium parameters. 1. General reading steps: Regardless of the type of flowmeter, it is necessary to confirm before reading: - Display unit: Confirm whether the screen displays cubic meters (m ³), liters (L), gallons (Gal), or mass units (kg/t). -Instantaneous flow and cumulative flow: There are usually "Flow Rate" or "Instantaneous Flow" and "Total" or "Cumulative Total" markings on the screen. -Medium parameter setting: For flow meters such as vortex street and electromagnetic flow meters, it is necessary to correctly set the density, viscosity, and other parameters of the measured liquid in the instrument, otherwise the reading will be seriously inaccurate. |Check the mechanical counter or electronic display screen. Pay attention to the influence of viscosity, high viscosity liquids can lead to low readings. ||Electromagnetic | Based on Faradays law of electromagnetic induction, measu
