1. What does "r" mean in an inlet flow meter? The "r" in an inlet flow meter usually represents the instantaneous flow rate (Rate), which is the volume or mass of water flowing through the pipeline per unit time. On the display interface of the vast majority of industrial instruments (including water flow meters), the letter r or abbreviation RATE is used to indicate the instantaneous flow rate value currently being measured. Its common units are cubic meters per hour (m ³/h), liters per minute (L/min), or gallons per minute (GPM), etc.

2. To help you quickly identify the status of the instrument, the following is a comparison table of common display symbols: | Display symbols | Representative meanings | Typical units | Explanation | |: -------------------------------------------------------------------------------------------------------------------------The total flow rate since the start of measurement | |% | percentage or flow rate |% | may represent the percentage of maximum flow rate or valve opening | | T (or TEMP) | temperature | ° C or ° F | if the flowmeter integrates temperature measurement function | 3 The most accurate confirmation method, as there may be slight differences among different manufacturers, is to refer to the high hail product manual or user manual of this model of flow meter. -Observing the cyclic display sequence of the instrument display screen, the instantaneous flow rate (r) and cumulative flow rate (V) are usually displayed alternately.

2. Where are the flow meters for measuring the inflow rate in sewage treatment plants generally installed? If you settle based on the amount of incoming sewage, install a flow meter at the sewage inlet pipeline of the main plant. If you settle based on the actual amount of treated water, install a flow meter at the qualified discharge outlet of the main plant. Try to require both the front and back drafts to be checked and installed. The inlet flow meter is installed at the rear end of the lift pump, with relatively stable pressure relief, and there should be a corresponding straight pipe section for velocity flow meters, which is conducive to the accuracy of measurement.

3. What is a pipeline flow meter?

A pipeline flow meter is a precision measuring device installed on the inlet pipeline of a pipeline water dispenser, used to monitor and control the water flow rate and cumulative flow through the pipeline in real time, ensuring the quantitative water intake, safety protection, and energy-saving operation of the water dispenser.

1. Core Functions and Working Principles 1 Flow monitoring: By using Hall effect or turbine sensing technology, the water flow velocity is converted into an electrical signal, and real-time flow (usually in L/min) and cumulative water consumption are calculated. 2. Quantitative control: linked with the motherboard, customized cup volume (such as 150ml/300ml) is achieved, and the water flow automatically stops after reaching the set value of the noise history. 3. Fault protection: monitoring abnormal water flow (such as long-term water flow or pipeline leakage), triggering automatic water cut-off and alarm, and preventing overflow or equipment damage.

II. Main Technical Types 1 Hall flowmeter: uses a magnetic rotor to rotate and cut the magnetic field to generate pulse signals, with low cost and strong anti-interference. It is standard for mainstream household models (accuracy of about ± 5%).
