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”

A stable flow field is the premise of the accurate measurement of the thermal instrument. Therefore,  please note the following points when installing the instrument. Installation direction Horizontal installation Vertical installation The process pressure must not exceed 2MPa when installing. Pipe requirements If the Interference sources (i.e. bends, reduce, valves, T tubes, etc.) exist on

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

Setting zero is the key for the nicety measurement of flow meters. After a primary meter installed, this operation should be done first. Steps as follows: After connecting the cable and power on the transmitter. About five seconds elapsed; automatically turn into normal operation menu, and display mass flow and gross. Keep for 5 minutes

Selecting correct specs of mass flow meters is the base for safe operation and accuracy measurement. Follow these selecting directions, could help you right use mass flow meters. Before selecting, should know parameters needed to select: flow range (maximum flow rate, rating flow rate, common use flow rate, minimum flow rate), line size (inner diameter,
