How to ensure the turbine meter scale sensor sensitivity

Abstract: how to ensure the turbine meter scale sensor sensitivity information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. In order to keep the display instrument of turbine, the sensitivity of sensor output pulse signal to have enough to improve the signal-to-noise ratio. To give full play to the characteristics of turbine flowmeter, must also be in the installation of the flowmeter using full attention, therefore, when installation. More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to ensure the turbine meter scale sensor sensitivity article details. In order to keep the display instrument of turbine, the sensitivity of sensor output pulse signal to have enough to improve the signal-to-noise ratio. To give full play to the characteristics of turbine flowmeter, also in the installation of the flowmeter using must be sufficient attention, therefore, when installation should guard against all kinds of electrical interference phenomenon, namely the electromagnetic induction, anti-static, and capacitive coupling. (1) flow rate distribution and the existence of the secondary flow is an important factor which affect measurement accuracy of turbine flowmeter. So, the turbine flowmeter of straight pipe upstream or downstream & ndash; On request. For industrial measurement, generally requires the upstream 20 d, 5 d downstream straight pipe length. (2) turbine flowmeter have higher request for the purity of the fluid and filter in front of the meter shall be installed to ensure clean fluid. Filter funnel type can be used, its cleanliness, measurable its differential pressure at the ends of the change. (3) to ensure that through the flowmeter is single-phase fluid, namely cannot let or steam into the air flow meter, flow meter should be installed upstream necessary gets over. For easy vaporization of liquid, the flowmeter downstream must ensure that the back pressure. The size of the back pressure desirable zui pressure drop under heavy traffic flow sensor twice and zui measured liquid under the high temperature steam pressure of 1. 2 times. To eliminate the secondary flow, adding rectifier zui to upstream end, there are about 20 d if the upstream end can guarantee the straight pipe, and adding rectifier, can make the measurement accuracy of flowmeter calibration accuracy of grades. In addition, the turbine flowmeter for high viscosity of hydraulic oil, engine oil, small diameter specifications can be used in a real flow calibration. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
