Description: Abstract: universal input, and various types of sensors, transmitters used in conjunction to achieve the required compensation of liquids and gases (such as saturated steam, superheated steam, general gas) flow measurement parameter display, alarm control, the instantaneous Flow Transmitter and cumulative flow totalizer; can receive input signals of various differential pressure orifice flowmeter input or vortex flowmeter, turbine flowmeter, electromagnetic flowmeter; there is prescribing, low-cut and multi-segment polyline input correction Optional features such as; separable switch the display screen before compensation instantaneous flow rate (or frequency), after compensation instantaneous flow, temperature, pressure and cumulative flow. 24VDC power supply can be provided for the three-way two-wire transmitter. Via serial communication port, you can read and write all of instrument parameters in the host computer. Technical data: The instrument uses the following units, users, such as the use of other units of the instrument shall be adjusted to the same unit. Frequency Unit: Hz temperature unit: ℃ Pressure Unit: MPa (display format X.XXX or XX.XX), special requirements optional KPa (display format XXX.X or XXXX). Fixed simply do flow cumulative time of 1 hour (h), do batch control unit can be set free: the accumulation rate. Instantaneous flow unit: parameter to define different units, such as cubic meters / hour, kg / h, t / h, etc., decimal point position can be set. Totalizer units: Units and resolution with the same instantaneous flow, for example: Assume that the instantaneous flow value remains 100.0t / h constant, if the accumulation rate time is 1 hour, the cumulative increase in traffic is 100.0t 1 hour. Flow Input Specifications: Frequency: 0 ~ 3200Hz, the signal level range 0 ~ 1V, high 3 ~ 24V voltage: 1 ~ 5V, 0 ~ 5V Current: 4 ~ 20mA, 0 ~ 20mA, 0 ~ 10mA Others: custom Special specification signal input (requires special customized) Temperature Input Specifications: Thermocouple: K (0 ~ 999 ℃), E (0 ~ 800 ℃), J (0 ~ 999 ℃) Thermal resistance: Pt100 (-200 ~ + 600 ℃ ) Voltage: 0 ~ 1V, 0.2 ~ 1V (respectively 100 ohms or 50 ohms external shunt resistor can achieve 0 ~ 10mA or 4 ~ 20mA input) Pressure Input Specifications: Voltage 1 ~ 5V, 0 ~ 5V (or 500, respectively, the European External 250 ohm can achieve 0 ~ 10mA or 4 ~ 20mA input) Accuracy: temperature, pressure, frequency, flow rate (without temperature and pressure compensation) measurement accuracy of 0.2% FS. Temperature and pressure compensation: superheated steam: temperature and pressure compensation (look-up table for temperature and pressure range: 150 ~ 590 ℃, 0.1 ~ 22MPa) General liquid: only temperature compensation, PA as compensation coefficients. Extended operation formula: allows users to customize special features calculation formula of temperature and pressure compensation calculation accuracy: typical operation error is less than 0.3% FS, the instrument as a whole after the operation typical error is less than 0.5% FS. Accumulate operation error: less than 0.01% Power Supply: switching power supply 100 ~ 240VAC / 50 ~ 60Hz; switching power supply 24VDC ± 2V Ambient temperature: 0 ~ 50 ℃ Power: <5W
