1、 Overview of Wall Mounted Ultrasonic Flow Meter
BR-2000S seriesultrasonic flowmeterIt can be paired with external clamp sensors, as well as plug-in and pipe segment sensors. External clamp sensors and plug-in sensors are available in both room temperature and high temperature types. Please choose the appropriate product based on your own usage environment.
2、 Product Features
1. The measurement linearity is better than 0.5%, the repeatability accuracy is better than 0.2%, and the time difference measurement resolution is up to 40 picoseconds, achieving a measurement accuracy of ± 1%.
2. The flow meter time difference analysis software developed with the assistance of 128 data acquisitions in each measurement cycle has excellent performance, displaying data more stably, accurately, and with better linearity.
3. Isolation type RS485 interface, flow meter and secondary meter can communicate through RS485 bus, with a transmission distance of over kilometers.
4. Equipped with 3 analog input interfaces with an accuracy of 0.1%, capable of connecting signals such as temperature, pressure, and liquid level.
5.1 4-20mA analog output can be used as a flow/heat transmitter.
The 2-way 3-wire PT100 resistor signal input can be used as a heat meter.
7.3 4-20mA analog input, can be used as a data collector, and the analog input interface can also be used as a digital input interface.
8. Equipped with dual isolated programmable OCT output, used for outputting cumulative pulses, working status, etc.
9. The measurement effect of sewage pipelines is good, and it can stably and reliably measure the vast majority of sewage pipelines.
10. Ultrasonic sensors can be selected from external clamp, plug-in, pipe section, and can also support water meter sensors installed at any angle, including parallel insertion sensors.
11. It has a bidirectional serial peripheral universal interface that can directly connect multiple external devices such as 4-20mA analog output boards, frequency signal output boards, thermal printers, data recorders, etc. through serial connection.
12. The working parameters of the flowmeter can be solidified into the FLASH memory inside the machine, without the problem of parameter loss. The working parameters for solidification can be automatically adjusted upon power on.
13. Hardware modular design. It consists of a motherboard module, 4-20mA output module, pulse output module, printer module, parallel port keyboard display module, serial port keyboard display module, etc. Users can choose according to their needs.
14. Different software communication protocols such as MODBUS protocol, MBUS protocol, FUJI extension protocol, and simple water meter protocol are available for users to choose from. The recommended protocol is MODBUS-RTU or MODBUS-ASCII protocol.
15. Daily accumulation can record the first 64 days, and monthly accumulation can record the first 32 months (2 years), with the addition of year month day recording content. The accumulated data of year, month, and day can be read out through the MODBUS protocol.
16.16 power on/off times recorded by flow meter. Data can be read out through the MODBUS protocol.
17. Timer printing and data output function, automatically displaying the next printing output time, with 22 programmable timed printing contents. The timed printing function can achieve automatic timed output or automatic recording of data.
The pulse width of the OCT1 cumulative pulse output can be set between 6 milliseconds and 1 second. The factory default value is 200 milliseconds.
19. Equipped with a keyboard display parallel interface, connecting display components can form a simple flowmeter.
20. The serial keyboard display component can be directly connected to the serial port, and can be plugged in and unplugged with power after parameter settings are completed.
21. It has the function of determining the type of fluid based on the sound velocity of the fluid, and can identify the type of fluid.
22. It has a programmable built-in quantitative controller. It can be started using external input signals or MODBUS commands.
23. A single 24V DC power supply operates with a current of less than 50mA. (Under the condition that the monitor is not connected and the buzzer does not sound).
