Third, the instrument classification
1. Press the instrument functional classification, JC-LWGY Series turbine flowmeter can be divided into two categories, namely:
• turbine flow sensor / transmitter
• Intelligent integration of turbine flowmeter
2. Function Description
• turbine flow sensor / transmitter
Kind of turbine flow product itself does not have on-site display, only traffic signal remote output flow signal can be divided pulse signal or current signal (4-20mA);. Low Meter prices, high integration, small size, especially for and the secondary display device, PLC, DCS and other computer control system used in conjunction.
Class turbine flow products divided into basic and explosion-proof (ExdIIBT6) are two, as shown in outline
Figure 1 Basic sensor / transmitter
Figure 2 explosion-proof sensor / transmitter
According to different output signals, such products can be divided into JC-LWGY- • N-type and JC-LWGY- • A type
JC-LWGY- • N-type sensor: 12 ~ 24VDC power supply, three-wire pulse output, high ≥8V, low ≤0.8V; signal transmission distance ≤1000 meters;
JC-LWGY- • A transmitter: 24VDC power supply, two-wire 4-20mA output signal transmission distance ≤1000.
• Intelligent integration of turbine flowmeter
Figure 3 Intelligent integration of turbine flowmeter
The use of advanced technology to develop ultra low-power single-chip microcomputer turbine flow sensor and display totalizer integration of new smart meters, with double LCD live display, with a compact body, intuitive readings clear, high reliability, without external power supply interference, anti-lightning, obvious low cost advantage. Meter with three meter factor correction coefficient nonlinear intelligent compensation instrument, and can be corrected on-site. High-definition LCD display also shows the instantaneous flow rate (four significant figures) and cumulative flow (8 significant digits, with clear function) All valid data after power for 10 years is not lost class turbine flowmeters are explosion-proof products, explosion-proof grade:.. ExdIIBT6.
Class turbine flowmeter in accordance with power supply, the availability of remote signal output can be divided into JC-LWGY- • B-type and JC-LWGY- • C type.
JC- LWGY- • B type: power supply with 3.2V10AH lithium battery (continuous operation for more than 4 years); no signal output.
JC-LWGY- • C Type: power supply with 24VDC external power supply, the output of a standard two-wire 4-20mA current signal, and depending on the site needs, increase the RS485 or HART communication.
