Flow meter

Relying on the advantages of small pressure loss and large detection range, it has become a very common flow measurement instrument in industrial control, which is not only easy to use but also has the advantage of strong compatibility. Especially suitable for low flow rate and small flow rate of the medium flow measurement. Rotor […]

Rotor flowmeter has a simple structure, reliable work, wide range of applications, accurate measurement, easy installation, and other characteristics, with high temperature and high-pressure resistance. Flowmeter operation in a common fault how to remove? I. No current output 1. First of all, see if the wiring is correct. 2. Whether the LCD has a display,

The development of flow measurement can be traced back to ancient hydraulic engineering and urban water supply systems. In the time of Julius Caesar in ancient Rome, orifice plates were used to measure the amount of drinking water used by the population. Ancient Egypt used the weir method to measure the flow of the Nile

In order to allow the rotameter to work properly and to achieve a certain measurement accuracy, the following points should be noted when installing the flowmeter.1. The rotor flowmeter must be installed vertically in the vibration-free pipeline. Fluid flow from the bottom up through the flowmeter, and the vertical degree is better than 2 °,

All-metal structure, with indication type, electric remote transmission type, corrosion-resistant type, high-pressure type, jacketed type, explosion-proof type. With 0-10mA, 4-20mA standard analog signal output, and field indication. Accumulation, digital communication, on-site modification of measurement parameters, different power supply functions, magnetic filter, and special specification varieties. Widely used in, petroleum, chemical, power generation, pharmaceutical, food, water

The variable area flow meter is suitable for the measurement of Process Alcohol HFO, LEO Defusel, Process Alcohol Refining Cut, and Process water. Such as the DN25 ATEX type variable flow meter with the following data for customers’ on-site measurement. Port diameter. DN25 Medium. Process alcohol Flow rate:100-1000L/H Temperature:90-120 C° Pressure:1.5-3 barg Density:0.88 Material:304 Display.

● Interference problem: Ask the instrument if there is an external power supply, if there is, remove both the external power supply and the signal line, and observe if it is zeroed with battery power only, if it is zeroed, there is interference and the interference measure that GND is connected to the case ground.

The pressure range selection is large, and the small field pressure cannot be collected. The pressure calibration parameters in the instrument have been restored to the factory settings (if the factory is restored, the voltage value in the P21-P25 screen will be 0.0) and need to be re-implanted. The D2 model is slow in collecting

If the temperature display is abnormally high when the battery is powered, the battery is dead. If the temperature display is below zero or much lower, the circuit board temperature chip is damaged and the board should be returned to the factory or a replacement board should be issued. Use a multimeter to measure the
