Intelligent Flow Totalizer

This instrument is used by the U.S. TI's MCU technology, combined with modern microelectronic technology developed by a common type, intelligent secondary instrument. It uses Segment digital display, intuitive and generous. The instrument set of automatic compensation, media flow computing, display and RS485/RS232 communications in one. With the work of high precision, stable performance, reliable operation, simple structure, strong anti-interference ability, easy operation and so on. It can complete a current-type flow sensors (such as: electromagnetic flow sensor, etc.), but also supporting the frequency-type flow sensors (such as vortex, turbine, oval gear and rotary piston flow sensors, etc.), but also for pressure, temperature and automatic compensation (subject equipped with Pt100 or temperature, pressure transmitter). Can be applied to all kinds of liquids, gases and steam volume, mass flow and temperature and pressure measurement of thermal parameters and control systems.
1, features
1, versatility
Mode 0. Apply to current output proportional to the flow sensor and flow.
Mode 1. Measuring liquids, gases and steam volume flow (without compensation).
Mode 2. Measuring liquids, gases and steam mass flow (without compensation).
Mode 3. Measurement of saturated vapor mass flow rate (pressure compensation). Look-up table calculation.
Mode 4. Measurement of saturated vapor mass flow rate (temperature compensation). Look-up table calculation.
Mode 5. Measuring the quality of superheated vapor flow (pressure, temperature compensation).
Mode 6. Measurement of gas volume flow under standard conditions (without compensation).
Mode 7. Measured under standard conditions of gas volume flow (pressure, temperature compensation).
Model 8. Frequency measurement and pulse counting.
2, allowing a variety of signal input
2.1. Current: 4 ~ 20mA
2.2. Voltage: 1 ~ 5V
2.3. Frequency: 0 ~ 9999Hz (positive pulse, amplitude: +2 V ~ +24 V, pulse low-level not greater than 1.2V). 0.00 ~ 499.99 Hz and 500 Hz ~ 9999 Hz to determine conversion automatically calculated.
3, with a density of auto-compensation function
3.1. Pressure automatic compensation
3.2. Automatic Temperature Compensation
3.3. Pressure, temperature at the same time automatic compensation
4, small-signal removal
Resectable caused by external factors, low-frequency interference into the string.
5, display strong
Shows the cumulative flow, instantaneous flow rate, pressure, temperature, frequency, current and other measurements.
6, printing
PP40 series can be equipped with printers or TPuP_A series printers, timing, or at any time print the corresponding measured data.
7, password latch function
Power meter, you must enter the appropriate password to enter the four parameter settings to prevent the independent officers to change the parameter settings, passwords, custom.
8, Alarm function
When the instantaneous volume above or below the set value, the output control signal, buzzer alarm.
9, the cumulative amount of quantitative output function
When the cumulative amount of the cumulative amount of time to set up, and stop the accumulation of the relay, buzzer call time 0.25 seconds.
4 can be set to an integer, decimal 4. In order to achieve precise control of output.
10, current output (standard second-or three-wire system)
0 ~ 10mA or 4 ~ 20mA selectable; also for 0 ~ 5V or 1 ~ 5V output.
11, communication function
This instrument RS-485 or RS-232 communication optional 9600 baud rate (half-duplex), 8 data bits, 1 stop bit, no parity.
12, with real-time Beijing.
13, with search functions. Can be found clear accumulated five times the amount of time and the recent power outages and power-off times.
14, rated instantaneous volume settings to prevent the stealing gas, and record the last five times to steal air time functions.
Because the instrument during operation, the cumulative volume is always a relatively fixed in a stable accumulation of the instantaneous volume, instantaneous value can not suddenly become smaller (in addition to a normal power off the table), when the transient is less than the rated transient set quantities shall be deemed to steal gas, and record the time.
15, power-off protection. Instrument operation results and the parameters set by the user will not be lost after a power interruption can be long-term preservation.
16, AC 220V power meter can also be DC +24 V power supply.
17, with Road +24 V or +5 V ~ +20 V adjustable power output,
E2 can provide 50mA output current, E3 can provide 85mA output current, output over-current, short circuit protection.
18, reliable electromagnetic compatibility design:
