Intelligent quantitative control flowmeter control instructions - focus on microfluidic control technology

The intelligent flow totalizer is internally programmed and used with various flow sensors, temperature sensors, and pressure transmitters. Flow measurement parameters for liquids, superheated vapors, saturated vapors, and general gases, cumulative calculations, transmission output, alarm control, data acquisition, and communications. At present, it is a comparatively piloted flow totalizer in China.

The intelligent quantitative control flowmeter integrated controller has the following main features:

1. Automatically calculate and accumulate mass flow and standard volume flow;

Second, can be set to small signal flow removal function (flow, differential pressure input value is less than the set value when the instantaneous flow is 0) and flow quantitative control function (the total flow of the total cumulative value is greater than or less than the set value output control signal);

Third, the following sensor types can be selected for programming:

(1) Input Δ P, P, T are differential pressure flow sensors, pressure sensors and temperature sensors

(2) Input G is a flow sensor (linear flow signal)

(3) Input Δ P is differential pressure type flow sensor

(4) Input f is a frequency type flow sensor

(5) Input G, T flow sensor and temperature sensor

(6) Inputs f, P, T are frequency-type flow sensors, temperature sensors, and pressure sensors

(7) Input f and P are frequency type flow sensors, pressure sensors

(8) Input & Delta; P, T are differential pressure flow sensors and temperature sensors

(9) Input f and T are frequency type flow sensors and temperature sensors

(10) Input G, T, P are flow sensor, temperature sensor and pressure sensor

(11) Input G and P are flow sensor and pressure sensor

4. Three kinds of compensation functions: automatic temperature compensation, automatic pressure compensation, automatic temperature and pressure compensation;

V. Multiple types of signal input:

Current: 0 to 10mA or 4 to 20mA

Voltage: 0 to 5V or 1 to 5V

Resistance: Thermal resistance PT100

Frequency: 0 ~ 5KHz

Sixth, the high-brightness LED data code tube can be selected, and the instantaneous flow parameter value and the flow cumulative value, the instantaneous flow parameter value of the channel, the current accumulated value, the accumulated value, the differential pressure measurement value, the pressure compensation measurement value, and the temperature compensation measurement are simultaneously displayed. The total accumulated value of the entire eleven-position flow such as the value and the frequency measurement value can also be switched to display the instantaneous flow parameter value. Display of current date and time;

PV shows the instantaneous flow rate value as the whole five digits (0~99999 words)

SV shows the cumulative flow value as the entire eight digits (0 to 99999999 words)

PV+SV shows the cumulative flow value is a full 11 digits (0 to 99999999.999 words)
