The analog flow meter is a flowmeter with the analog output signal. Analog output is a common function of flow meters. The analog signal is mainly used to output the flow signal to the next control system.
Analog signal: poor confidentiality, weak anti-interference ability.
Digital signal: strong anti-interference ability and good communication confidentiality.
Digital signal, as the name implies, means that the independent variable is discrete. And the dependent variable is also a discrete signal. The independent variable of a digital signal is represented by an integer. Its dependent variable is represented by a limited number. The digital signal uses two physical states to represent 0 and 1. Therefore, the quality of the digital signal is very strong, and the anti-interference ability is also relatively strong.
The analog signal refers to the continuous signal of the information parameter in a given range. The characteristic quantity of the information of the analog signal can be transformed into an arbitrary numerical signal in an instant. In the process of transmitting analog signals, the information signals need to be converted into electric wave signals, which are then transmitted through wired or wireless methods.
If you need to know the flow rate in you pipe, or river, that when you need a flow meter. So, flow meter is the instrument that can finish the flow measurement.
Flowmeters consist of a primary device, transducer and transmitter.
The transducer senses the fluid that passes through the primary device.
The transmitter produces a usable flow signal from the raw transducer signal.
These components are often combined, so the actual flowmeter may be one or more physical devices.
Different types of flow meters are available for different applications, and depending upon the requirement, a careful selection of flow meters is made.
For e.g., we prefer vortex flow meters flow steam flow measuremnet. And we like the ultrasonic flow meters for non-contact pipe flow measuremnt.
A turbine-type flow meter cannot be used for measuring the flow in an unclear liquid (wastewater or corrosive liquids).
A flow meter (or flow sensor) is an instrument used to measure the linear, nonlinear, mass, or volumetric flow rate of a liquid or a gas. When choosing flow meters, one should consider such intangible factors as familiarity of plant personnel, their experience with calibration and maintenance, spare parts availability, and mean time between failure history, etc., at the particular plant site.
It is also recommended that the cost of the installation be computed, only after taking these steps different sensors include dial, in-line, ultrasonic, orifice plate, totalizing meters, variable area, venturi, or switch output. The different designs of the flow meters have a variety of applications.

Industrial digital chart recorders refers to an electronic instrument that remotely displays and counts signals such as pressure, temperature, flow, and liquid level in the industry.
Digital chart recorders record the collected data/calculated data in the internal storage system of the instrument with time as the base axis. It does not consume any commonly used recording facilities. For example: paper, pen and ink. Sino-Inst provides time-saving paperless chart recorders with up to 64 channels.
The stored data recorded in the instrument is displayed on the LCD screen after calculation and simulation. Commonly used LCD screens are widely used. On the LCD screen, digital display, bar graph display, curve display, alarm list, etc. can be displayed.
The data collected by the paperless recorder are commonly used: temperature, pressure, flow, liquid level, voltage, current, humidity, frequency, vibration, speed, etc.
Paperless recorder working principle
The paperless recorder is mainly composed of industrial special microprocessor, A/D converter, read-only memory ROM, random memory RAM, display controller, liquid crystal display, keyboard controller, alarm circuit, clock circuit and other parts.
The paperless recorder is based on a single-chip microprocessor. Collect and process various data. The recorded data can be sent to the random memory RAM for storage. Or send it to the LCD display for display. It can also be zoomed in or out as needed. To facilitate the operator to observe the status of the recorded signal.
At the same time, the recorded signal can be compared with the set upper and lower limit signals. Once the limit is exceeded, an alarm signal will be issued.
The A/D converter converts the analog quantity from the recorded signal into a digital quantity for the CPU to perform arithmetic processing.
The read-only memory ROM is used to solidify the program. After turning on the power, the ROM program can make the CPU work.
Random memory RAM is used to store historical data processed by the CPU. Depending on the sampling time, the data can be stored for several days to several decades. It has a backup power supply to ensure that all recorded data and configuration signals will not be lost due to power failure.
The data in the CPU can be displayed on the LCD screen via the display controller. Generally, it can be displayed on a 7-inch or 10.2-inch color LCD touch screen.
The operator makes various settings by operating the keys or the touch screen. The signal is transmitted to the CPU, so that the CPU works according to the requirements of the operator.
When the recorded data exceeds the limit, the CPU sends a signal to the alarm circuit in time to generate an alarm output. The function of the clock circuit is to generate the recording time interval, time stamp or date required by the recorder and transmit it to the CPU.
In addition, the paperless recorder is also equipped with a print controller and a communication controller. The data in the CPU can be connected to external miniature printers and personal computers through them. Realize data printing and communication.
