When to use a peak flow meter:Every morning before you take your asthma medicine Before and after you take rescue medicine for an asthma attack or worsening symptoms Other times during the day as directed by your healthcare providerHow to use a peak flow meter:...
An experiment (Table I) was carried out to demonstrate the possible errors in flare flow measurement using different types of flowmeters with different gas compositions. Because of the accuracies demonstrated in Table I and the above considerations, this article focuses on the...
Here's how to use a multimeter to test an electric appliance: 以下是用万用表测量电器设备的简单步骤: 1.除非需要带电进行测量,其余情况下必须将电源切断。 2.将万用表表棒与万用表相连接。 3.选择测量档位,如交流电压、直流电流、电阻等,和适当的量程。 4.将表棒与被测电器的导线或者元件相连。 5....
Provided is an ultrasonic flowmeter capable of easily replacing the flow rate measuring tube and preventing the flow rate measuring tube from falling off. The ultrasonic flow meter 20 of the present invention measures the flow rate of a liquid based on the difference in propagation time of ...
Turbine flow meter is a kind of velocity flow meters. They use a multi-blade rotor (turbine) to sense the average flow rate of the fluid to deduce the flow rate or total volume. The rotational movement of the rotor can be detected by mechanical, magnetic induction, optical or electronic ...

How to choose and buy flow meter 每种流量计的原理和特点不同,致能够测量的介质、精度、安装要求等都不同,需要采购人员或技术工程师根据测量现场的具体工况选择对应的流量计.现场提供的参数越详尽,对于流量仪表的选择越有帮助.流量计的选择需要确认以下几个方面:...
However, Sierra’s QuadraTherm® thermal mass flow meters deliver accuracy as good as, if not better than, Coriolis meters with a single device at a fraction of the price. Raw and Untreated Fluids Where unfiltered or untreated fluids are being handled it is best to use robust, less ...
Oval gear flow meters are suitable to measure high viscosity liquids, users need to generally heat the fluids to flow when start to use the flow meter again. When the flow meter is stop working, its internal fluids is cooled and thickened. When it is working again, cooled fluids must be ...
If you're measuring DC voltage (such as a battery or a sensor hooked up to an Arduino) you want to set the knob where the V has a straight line. AC voltage (like what comes out of the wall) can be dangerous, so we rarely need to use the AC voltage setting (the V with a wavy...
