Turbine meter scale of medium viscosity requirements and check items before installation

Abstract: the turbine meter scale to the requirement of medium viscosity and before installation inspection information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Well-known flowmeter of turbine flowmeter, displacement meter and three types of coriolis mass flowmeter is repetitive, high accuracy of flow measurement instrument, and turbine flowmeter has its own characteristics, such as simple structure, less processing parts, light in weight. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the request of turbine flow meter scale to medium viscosity and installation check items before the article details. Well-known flowmeter of turbine flowmeter, displacement meter and three types of coriolis mass flowmeter is repetitive, high accuracy of flow measurement instrument, and turbine flowmeter has its own characteristics, such as simple structure, low processing components, light weight, convenient maintenance, adapt to large flow capacity and high parameter, etc. Due to mechanical turbine eccentric and frictional resistance moment of tiny change, the influence of the turbine flowmeter in the same rotation cycle occurs periodically speed change, that make it hard for the turbine to a very low speed, stop running because of the highly vulnerable to disturbance at this time. Viscosity influence on turbine flowmeter: 1, for stripper well produced fluid viscosity is higher, appropriate USES acquisition system makes it more sensitive turbine can be accurately collecting low speed ( Less than zero. 01 r / s) The signal. 2, before entering the turbine response of linear segment, K values continue to rise, and with the inlet Reynolds number flow meter, exponential relationship. 3, with the enhancing viscosity and K value of the turbine flowmeter will decline, also will become worse linearity. 4, with the increase of viscosity, the start of the turbine flowmeter displacement decreased, while the response of zui low speed will decline. 5, is used to measure the turbine flowmeter of different viscosity fluid, only on a down the condition of high viscosity flow Reynolds number, different calibration can approximate the turbine flowmeter K value and the relationship between the Reynolds number, and deduced the turbine of the response curves of different viscosity fluid. Turbine flowmeter in the device and the use of the chapter, there are a lot of small problems, but must pay attention to these details, talent ensure accurate flow measurement accuracy. Many details if don't pay attention to, the use of time is difficult to find the problem, now is easy to ignore the problem are summarized, the hope can get everybody's attention. 1, the requirement of pipe, the inner diameter of the turbine meter device point of upstream and downstream piping is the same as the meter diameter. 2, the requirement for straight pipe: flowmeter degree of necessary device in the line, Tilted pipe within 50) Axis, the device when the flow meter should be concentric to the pipe axis, flow to divide. Meter length upstream pipe should be not less than 2 d straight pipe sections, such as place if the device allows initiative for 20 d straight pipe upstream and downstream of 5 d. 3, the requirement to the by-pass pipe: liquid turbine flow JiJi overhaul in order to ensure not affect the normal use of medium, the flowmeter should device to cut off the valve in the pipeline before and after ( Globe valve) The by-pass pipe shall be set up, and at the same time. Flow control valve to device on the downstream side of the flow meter, flowmeter using the upstream on the cut-off valve must be fully open, prevent local upstream fluid unsteady flow phenomena. 4, the request of the external environment: good flowmeter zui device indoors, must device outdoors, be sure to use prevent bask in, prevent the rain. Lightning protection measures, so as not to affect use life. In the medium containing impurities request: in order to ensure the using life of turbine flow meter, should be installed in front of the straight pipe of the flowmeter filter. 5, at the request of the selection: selection within the scope of the rule of flow, avoid overdrive, to ensure that had good accuracy and ensure the normal use life. Turbine meter before the operation is not allowed to arbitrarily. Back cover, change the internal related parameters, otherwise will affect the normal operation of flowmeter. Beware of device gaskets, make sure there are no outstanding content into the pipeline, in order to avoid interference with the normal flow measurement. When flowmeter calibration to collect pressure on the flow meter to take pressure. Before turbine flowmeter in front of the device should be clutter: clearing the pipe pieces, welding slag, stones, dust and other referral in the upstream device 5 micron mesh filter used to prevent droplets and grains of sand. Flowmeter of commissioning should slowly open valve before first, when after open the valve, avoid turbine for air impact and damage. Add smooth oil should be according to the sign, the number of refueling depends on temperament clean level, usually 2 - every year 3 times. Due to pressure test, purging pipes or exhaust turbine overdrive formation, and operation in the reverse flow turbine impeller damage will likely make flowmeter. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
