How to choose marine flow meter?
Flow meter is a kind of instrument used to measure the flow of liquid, gas, steam and other media in the pipeline. Different types of flow meters have their own advantages and scope of application, how to select the type is the introduction of equipment must be considered. In order to make a reasonable choice, it is necessary to consider from the application requirements, flowmeter type, accuracy and measuring range, installation requirements and economic factors.
Overview
According to the fluid properties selection, gas and liquid with gas type and liquid type, can not be generalized. Under the working condition, the viscosity of the liquid is more than 5mPa.s. The high viscosity type should be selected. Acid corrosive liquid selection of acid-resistant type.
Ambient temperature and humidity, such as selecting the appropriate instrument, such as the surrounding explosive and flammable atmosphere should be selected explosion-proof sensor.
The devices can be installed horizontally or vertically. Horizontal installation and pipeline connection with flange connection, threaded connection and clamping connection. Medium caliber flange connection, small diameter and high pressure pipeline selection of threaded connection, clamping connection is only applicable to low pressure small and medium pipe diameter. Vertical installation only threaded connection.
According to the site conditions, such as flow range, pipe diameter, fluid pressure and temperature, installation location and performance requirements, such as accuracy, repeatability, display mode, etc. Refer to the manufacturer's selection samples or instructions for the selection of specific specifications and models, or may not be able to find the right one, you have to choose another flowmeter.
