1. What does the water treatment flowmeter r represent?
The "R" in water treatment flowmeters usually represents the instantaneous differential flow rate (Rate), which is a key parameter for real-time monitoring of fluid flow velocity in pipelines The core meaning of "R" is to indicate the instantaneous flow rate in the display screen or output signal of most water treatment flow meters (such as electromagnetic and ultrasonic flow meters), usually in units of m ³/h (cubic meters/hour) or L/min (liters/minute). It reflects the current flow rate, which is different from the cumulative flow rate (usually marked as "Total" or "∑")
2. Common identification scenarios - Electromagnetic flowmeter: The screen displays "R=100.5 m ³/h" and the meter vertically displays an instantaneous flow rate of 100.5 cubic meters/hour - Control system: In the 4-20mA analog signal output, "R" corresponds to the real-time flow value - Alarm setting: The device allows setting a threshold for the instantaneous flow rate "R" (such as ultra-high/ultra-low flow alarm). 3 Attention should be paid to the manufacturer differences. Some brands may use "R" to represent other parameters, which needs to be confirmed in conjunction with the equipment manual: - In rare cases, it may represent the flow range (Range) or signal ratio (Ratio) - The "R" in some models of Rosemount indicates the percentage flow rate (% Rate). 4. Operation suggestions - Refer to the parameter table in the corresponding model manual to confirm the specific definition of "R" - Switch the display mode through the device menu and observe the numerical changes (instantaneous flow usually fluctuates dynamically, cumulative flow increases unidirectionally) - During calibrat
2. WTG-DC series intelligent electromagnetic flowmeter user manual: [1]
The core content of the WTG-DC series intelligent electromagnetic flowmeter user manual is as follows:
1. Product Overview WTG-DC series intelligent electromagnetic flowmeter is a high-precision flow measurement instrument based on Faradays electromagnetic induction law, suitable for measuring the volume flow of conductive liquids (such as water, acid-base solutions, slurries, etc.).
. The product has the characteristics of intelligence, high reliability, and strong anti-interference ability, and is widely used in industries such as chemical engineering, metallurgy, water treatment, and food.2. Installation Requirements Environmental Conditions: The installation location should be far away from strong magnetic fields and vibration sources, avoiding direct sunlight or direct rain. The ambient temperature should be between -20 ℃ and+60 ℃.
. Pipeline requirements: The flowmeter should be installed horizontally or vertically (when installed vertically, the fluid direction should be from bottom to top), ensuring that the pipeline is filled with liquid and free of bubbles. Before installation, it is necessary to clean the welding slag and debris inside the pipeline to avoid damaging the sensor lining. Grounding requirements: The flowmeter casing and monitoring sensor m
