Vortex flowmeters measure a fluid flow’s velocity. The vortex shedding frequency governs the vortex flow transmitter. A technician compares the output vertex flow frequency with the signal of the input pulse using a calibrator that serves as a master calibrator. The essential steps in the vortex flow calibration are as follows: Step 1: Calculating the […]

The signal indicates that this field is adjustable Flow rate unit is selectable from g/min、g/s、 Kg/min、 Kg/h、 Nm3/h、Nm3/min、NL/h、NL/min、SCFM Cumulative flow unit could be one of: g、Kg、Nm3、NL、CFM， The cumulative flow unit is changed with the flow rate unit setting and therefore does not need to be set separately. The screen display is as follows:

(Unit: Nm3 /h. The following table can be extended) Nominal Diameter (mm) Air Nitrogen（N2） Oxygen（O2） Hydrogen(H2) 15 65 65 32 10 25 175 175 89 28 32 290 290 144 45 40 450 450 226 70 50 700 700 352 110 65 1200 1200 600 185 80 1800 1800 900 280 100 2800 2800 1420

According to different gas on-site, the calibration in the lab translates the flow rate of actual gas on-site into the flow rate of air and then begins to calibrate the flow rate at present. Therefore, when using the meter on-site, the meter displays mass flow or volume flow of actual gas. When translating the flow

Before any hardware repair, please ensure all the following points are correct as these affect the performance Check if the instrument is correctly supplied with power. Check if the instrument wiring is correct against Chapter 2. Check the straightway lengths are properly set as described in Chapter 6.2. Check if the actual flow direction is

Pipe requirements If the Interference sources (i.e. bends, reduce, valves, T tubes, etc.) exist on the instrument intake pipe, measures must be taken to minimize their impacts on measurement performance. The following diagrams describe the recommended minimum straightway lengths of some types of pipe. The straightway length should be as long as possible while the

The thermal mass flowmeter is a precision instrument that is produced by the latest technology and technology. Improper installation and use can lead to abnormal and damage to the instrument and even the process control equipment. Engineers and technicians who install, set up, and connect the product must read this manual carefully before using the

Troubles Reasons Removing Value of dp is not steady Installation was incorrectness Install again follow 5.1 DP is sometimes big or small Setting Zero was of no effect Check-up connection between the transmitter and the sensor Display “Vibration Stops” Bad connection, or dirty inner tube Check-up connection or clean inner tube Display “Density Too Low”
