NONCON Instrument is mainly engaged in the development, production, sales and service of high-performance, intelligent instruments and related systems.The products include vortex flow meter, turbine flow meter, electromagnetic flow meter, mass flowmeter, metal float flowmeter, roots flowmeter, ultrasonic flowmeter and air energy consumption metering management system, IC card energy metering management system, steam metering management system, air conditioning energy management system, gas metering management system, etc.

The choice of flowmeter is much more complicated than that of other instruments, because there are many kinds of flowmeters and none of them can be applied to any fluid, any range and any condition.Each kind of flowmeter has its specific use, has its limitation, the flowmeter choice is improper, the flow rate is impossible to measure accurately, how to choose a suitable flowmeter for the application situation is very important.NONCON tips to choose a flow meter to consider the state of production process, the characteristics of the measured flow and the characteristics of the flow meter, flowmeter installation environment and conditions, whether to facilitate future maintenance and repair and other issues.

Measuring process media are diverse, and the instrument and fluid contact, mostly in the harsh conditions of the site, with the passage of time, the detection element is corrosion, wear, scale, blockage, etc., will make the instrument measurement error increase, leading to the decline of measurement accuracy, until the failure.In addition to strengthening maintenance, how to choose stable quality, high reliability of the flow meter is also very important.

The practical and economical aspects should be taken into account in the selection of specific flowmeter.Consider the types of flow bodies to be measured in process production, such as gas, liquid, steam, etc.;Its working state, such as temperature, pressure, etc.Properties and related parameters, such as density, viscosity, conductivity, corrosion, etc.;Is it single-phase flow, two-phase or multi-phase flow?Maximum flow and minimum flow;How much pressure loss is allowed;Requirements for measuring accuracy;What are the installation and use conditions on site?What is the purpose, such as indicating, measuring, recording, control, etc.Consideration should also be given to whether the meter price is subject to investment restrictions.

The selection of the flow meter can usually be selected according to the following steps, first determine the measured media is what, its working temperature, how much pressure, measurement requirements is to measure or show, record, control;And then set the upper limit of measured flow rate at the beginning of this step requires flow scale conversion work, namely the work be the actual traffic flow under the condition of scale conversion into water or air traffic, again after conversion in accordance with the flow rate to determine the upper limit value, the flow of the work is to use the formula and chart, specific content can be reference related books for flow measurement.Next can choose and determine the flow of the measurement range, to the choice of caliber, and finally determine the choice of the measurement method and flow meter, and preliminary accounting of the investment.No big problem is basically determined, otherwise should return to the relevant steps to re-select.
