. VFM5 Vortex Flow Meter Flanged type Wafer type Insertion type VFM5 is a powerful flow meter utilizing Karman vortex theory, which can meet the requirement of measuring the flow rate of various fluids such as gas, steam and liquid. The product uses the VFM5 transmitter technology, which provides with the excellent signal processing capability and enhance the vortex metering technology to a new level, which means it has lower measuring limit, better stability and accuracy. The special signal processing method has also ensured a better anti vibration by eliminating the vibration signals. The VFM5 platform is also an open platform, which means we can keep on upgrading its function according to customer s unique requirement, and make the product a highly custom orientation product. Sensor design that free from maintenance. Self density calculation function is optional, can calculate density and mass flow rate without mass flow computer. Can output mass flow rate, temperature and pressure by working with separate RTD and pressure transmitter T&P compensation programmed model available,can temperaturee and pressure sensor to measure mass flow direct work with separate Can output mass flow rate, temperature and pressure by working with RTD and pressure transmitter. Unit selectable function, meet different requirement on reading s units. DIN, DN, ANSI, JIS flange for option, can fit in any process connection. Many other options, such as 0SS and SS, insertion, wafer and flanged, different compensation method, different output methods. Customer can find the most suitable model to save cost.

) Other ordering information required To ensure the customer find the right product which can fit in the application, it would be better if below information is provided with. a. Detailed fluid introduction. What is the fluid (air or steam or N or )? The viscosity and density of the fluid, the accurate process pressuree and temperature ranges of the fluid are all very important. This information is required before we can know if our flowmeter can be used in the fluid and what other treatment should be chosen b. Flow rate. As indicated in earlier section, our measurement range is a 0: range in 0.5~7m/s for liquid, 5~70m/s for gas and steam, which are alll velocity range. If the flow range customer required is volume range (m/hr, l/min) or mass flow rate (kg/hr, lb/hr, tons/day),we have to transfer them into velocity range. If the requirement of customer is a mass flow range, we have to calculate the density of the fluid base on the process pressure and temperature, than transfer it in to volume flow range and finally to velocity range. To know the process density of saturated steam, please reference to the appendix of density table of saturated steam. c. If the fluid is O, the wetted parts have to be degreased.also we can do the degreasing in our workshop, we strongly recommend customer to do it again at field before installation. d. For wafer type, we will provide counter flanges which will be welded to the pipe during installation, thus customer should advise the material of the process pipe line. Our counter flanged will be made in the material same as the process pipe line to ensure a reliable welding. e. For wafer type, we will provide customer along with screws and bolts for installation. But for flanged type, as all bolts and screws are standard parts, customer can prefer to buy them in local market to save the cost of transportation. f. For flanged type, customerss need to advise the type of the flanged. g. If customer should have any other inquires or special requirements, please be free to check with our engineer or sales person. ) Example of a model selection Application: Saturate steam, process pressure 0.Mpa.
