| Click to download LSD-B1 Intelligent Flow Totalizer Manual 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 |
