Flow meter

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

● Since D2 is a dual power supply, to determine whether 24V is properly powered, unplug the battery or test with a multimeter. ● Pulse equivalent post terminal dial code 1 to ON, 2, and 3 to OFF. ● Pulse active output, whether PNP type is matched with the site. ● Measure the voltage between

● Since D2 is a dual power supply, to determine whether 24V is properly supplied, unplug the battery or test with a multimeter. ● Pulse equivalent after the terminal dial code 2 set ON, 1 and 3 set OFF, equivalent parameters refer to the manual optional ● Pulse equivalent active output, whether PNP type is
