Introduction to metal hose and how to use

Various calibers of pipeline metal hose although there are its commonalities, such as the general requirements are full pipe flow, most of them can output standard signals, can also display the flow value in situ, etc., but more is each has its own characteristics. Such as the measurement range, flow rate, measurement accuracy, the requirements of the installation conditions. Therefore, the use conditions and requirements should be considered comprehensively, combined with the characteristics of various metal hoses to choose, so that the characteristics and advantages of metal hoses to give full play to the purpose of applicable, economic and convenient.
 
How is the quality of water flow is the first issue to consider when choosing metal hose. For example: containing mixed water or sewage, generally should not choose volumetric metal hose; sand or water temperature changes when the metal hose measurement accuracy will be affected; measuring the flow of corrosive fluids should choose not to contact the fluid outside the clamping ultrasonic metal hose or capacitive induction electromagnetic gauge; water containing debris should not choose turbine, vortex street, rotary slurry, differential pressure type or volumetric metal hose. Metal hose flow measurement range is not only related to the choice of metal hose size, but also related to the conditions of use of metal hose and the guarantee of measurement accuracy. In general, the metal hose selection design information will provide a certain caliber of metal hose measurement range, and the accuracy of the metal hose is generally only within the range of its test curve to ensure that outside this curve, the metal hose can still measure the flow.
But the measurement accuracy decreases, and even to cause damage to the metal hose. Therefore, in the selection of metal hose, the flow range of metal hose should be done in mind. Metal hose flow rate of change is also the choice of metal hose should be considered. If the water pipeline water flow changes, because they are relatively large flow rate of change, can meet the use of the requirements.
