Abstract: to install ultrasonic open channel flow note information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 1, precision grade and function in accordance with the requirements of measurement and choose the instrument using fine grade, cost-effective. Such as for trade settlement, product transfer and energy measurement occasions, should choose high precision grade, such as 1. Level 0, 0. Level 5 or higher. More flow meter manufacturers choose model price quote you are welcome to inquire, here is to install ultrasonic open channel flow considerations article details. 1, precision grade and function in accordance with the requirements of measurement and choose the instrument using fine grade, cost-effective. Such as for trade settlement, product transfer and energy measurement occasions, should choose high precision grade, such as 1. Level 0, 0. Level 5 or higher level; Used in process control, according to the requirements of control choose not with precision grade; Some just check process flow, without having to do precise control and measurement, can choose lower precision grade, such as 1. Level 5, 2. Level 5, and 4. Level 0, then can choose low prices of plug-in open channel flow meter. 2 with the diameter measurement, measurement medium velocity, full scale general medium, the full flow of open channel flowmeter can measure medium velocity in 0. 5 - Choose 12 m/s scope, range is wide. Select instrument specifications ( Diameter) Differ and process piping, the same shall consider whether flow range within the scope of the flow velocity in measurement, namely when the pipeline flow rate is low, can not meet the requirement of the flow meter, or under the velocity measurement accuracy of the quasi cannot guarantee, the need to reduce the size instrument, which carry high tube flow velocity, measurement results are satisfied. 3, fluid characteristics, mainly refers to the gas pressure, temperature, density, viscosity and compressibility, etc. , due to the volume of a gas changes with temperature, pressure, should consider whether to offset correction. 4 refers to the precision of the instrument, instrument performance, repeatability, linearity and range ratio, pressure loss and initial flow rate and the output signal and the response time and so on, choose flow timing to deal with the above index for detailed analysis and comparison, the selection can satisfy the requirement of measuring medium flow meter. 5, is refers to the gas flow, piping installation conditions, upstream and downstream straight pipe length, diameter, space location and pipe fittings, etc. , these will affect the gas gas flowmeter accurate operation, maintenance and service life. 6, economic factors is to point to purchase expense, installation, maintenance, calibration and spare parts, etc. , and its gas gas flowmeter effects such as performance, reliability and life. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
