Selecting the proper technology for your application requires writing a flow specification which covers the use of the meter. There are usually trade-offs with each meter type, so knowing the critical specifications will be important.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">Things you must know:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">What is the Gas or Liquid being measured?<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">Minimum and maximum flow rates.<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">What are the accuracy requirements?<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">The fluid temperature and viscosity.<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">Fluid compatibility with the materials of construction (See our materials compatibility guide)<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">The maximum pressure at the location.<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">What pressure drop is allowable?<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">Is the meter mounted in a hazardous location where explosive gases may be present?<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">Is the fluid flow continuous or intermittent?<\/span><\/li>\n<li><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">What type of output signal or readout do you need?<\/span><\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; font-size: 14pt;\">Use your collected information to eliminate the technologies that do not apply (ex. Turbines don\u2019t work for viscous fluids, Coriolis meters don\u2019t respond fast enough for injection flow, Positive Displacement meters aren\u2019t economical for large pipe diameters like a 12 inch diameter line.). You will then have a comparison of the remaining technologies. Accurate meters are priced based on their capabilities. It is better to locate the type of meter which fits your application before trading features for cost savings. Closely evaluate your extreme conditions, such as low flow rates, high pressure or temperature, or the need to measure over a wide operating range. If these conditions are critical to quality for you, do not use lower priced alternatives applied outside of their capabilities.<\/span><\/p>\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>A flow meter is a device used to measure the volume or mass of a gas or liquid.\u00a0 Flow meters are referred to by many names, such as flow gauge, flow indicator, liquid meter, flow rate sensor, etc. depending on the particular industry.
