(Revised time: 03 September 2024) YFGRW2000B Gear Flow Meter User manual Please read the user manual carefully before using the product

1. product presentation: YFGRW200B wireless gear flowmeter is a new type of volumetric flowmeter developed according t o the principle of gear motor, which is used for precise continuous or intermittent measurement of liquid fl ow in the pipeline. It is suitable for flow measurement of heavy oil, polyvinyl alcohol, resin and other medi a with high viscosity, and small flow can be accurately measured. Working principle and structure: There are a pair of engaged gears in the flowmeter cavity as a rotor, two gears and cavity can respectively constitute a fixed volume, called the standard volume,...

■ High sensitivity measurement ■ Resistance to high pressure, high and low temperature resistance ■ High-precision measurement with excellent repetition accuracy ■ In a wide temperature range, the output signal is not affected by the temperature ■ High precision is still maintained at the lower limit of the low flow rate measurement range ■ High operational reliability of the electronic components ■ The preamplifier terminal is easy to use

■ Please indicate the medium and the minimum flow rate, different viscosity medium, the minimum flow rate range is different ■ There is a magnet inside the gear, measuring the media containing iron ions is prone to lag problems, please use with caution ■ Precision description: range ratio 1:10, accuracy 0.5% specification and dimension model

Hosman Digital Signal Output: With the display of full ■ Frequency wiring: 24 power supply F + and F-, frequency wiring ■ 485 wiring: 24V power supply F + and F-485 wire A and B. ■ Current wiring: if the customer site system is two-wire 24V + connected to I +, the current line is connected to I-. In three lines, the 24V + is connected to I +, the current line is connected to I-, and then the current line and the GND of the 24V power supply are short connected together in the system. In the four-wire system, 24V + is connected to I +, the current line is connected to I-, and then the system 24V...

七、 Display and menu After the power is turned on, the instrument first self-tests and enters the working main display state of screen 1. 0 0 0 0 0 0 0 0 .Nm3 First line: self-test storage function normal sign, with LCD letters for backlight open state. Second row: instantaneous flow rate. Line 3: cumulative flow. Fourth row: flow rate display, need to set the caliber before the display. Keynote: The circuit board can be found through the appearance of three keys exist, their functions are: SHIFT：a、 Switch the screen. You can switch this to the menu screen on the main screen. b、 Switch between...

enter Parrword: XXXX I No'te: Pressure and temperature compensation instrument, do not show pressure and temperature, only show frequency Production calibration function (calibration output current signal, no standard input entry) • The production and adjustment of the instrument should be carried out by professionals with a deep understanding of the instrument under tire condition of calibration equipment with corresponding accuracy. In the second line system, there should be at least a range> 20 mA, an accuracy better than 0.1% • Production adjustment and some advanced Settings are carried...

01 is the device communication address, 03 is the function code, 00 00 is the starting register address, 00 0E is the register length, and C4 0E is the CRC check code. 01 is the mailing address of the device, 03 is the function code, 1C is the number of bytes (0E is 14 registers, each register two bytes of 28 bytes) 2AA7 3F 60 is the 11th and 12th registers back, representing the cumulative flow below 100 bits need to be rearranged and resolved (order 3412) That is, 3F 60 2A A7, the analytical number and software reading is 0.87565.

♦ The site installation position of the transmitter should avoid as far as possible the large temperature, large mechanical vibration, strong magnetic field interference, corrosive environment, should choose easy maintenance position installation; ♦ The transmitter should generally be installed horizontally, and the sensor must be firmly installed on the assembly body with screws. If it must be mounted vertically, the liquid direction must be upward. The liquid shall be filled with pipes, with no air bubbles; ♦ The type of transmitter accessory is installed, the base center line should be aligned...

valve with medium opening, then slowly open the downstream valve, close the opening of the bypass valve, make the transmitter run with a small flow for 10 minutes, and then fully open the upstream valve fully closed bypass valve (to ensure no leakage), and finally adjust the opening of the downstream valve to the required normal flow; • When opening and closing the valve, it should be gentle, such as automatic control opening and closing, especially for the large diameter sensor best "two segments open, two segments close", to prevent the sudden impact of liquid water hammer effect resulting...
