Hongrun launches flow totalizing controller

Hongrun launched the flow totalizing controller

nhr-5600 series flow totalizing controller, which collects, displays, controls, remotely transmits, communicates and prints various signals such as field temperature, pressure and flow, forming a digital acquisition system and control system, which is applicable to the flow totalizing measurement and control of liquid, general gas, superheated steam and saturated steam

double screen LED digital display, with extremely wide display measurement range, can display the instantaneous flow measurement value, temperature/pressure compensation measurement value, flow (differential pressure, frequency) measurement value of the whole five digits, and the cumulative flow measurement value of the whole eleven digits, with a measurement accuracy of 0.2%

with 37 kinds of signal input functions, it can be equipped with various differential pressure signals (orifice device), linear signals (electromagnetic flowmeter) and pulse signals (vortex flowmeter), and can freely select a variety of compensation methods (temperature compensation, pressure compensation, temperature and pressure compensation, etc.)

the table lookup method is used for density compensation, which can automatically control the integration of superheated steam and saturated steam with high precision, and a variety of flow integration formulas are built in, It is suitable for various measurement occasions and has the function of automatic calculation of flow coefficient K

simple fault-tolerant function: when the temperature and pressure compensation measurement signals are abnormal, the corresponding manual setting values are used for compensation operation

the specially designed WDT circuit, power on reset circuit and power-off data protection circuit ensure the normal operation of the instrument when powered on; Built in 33V dry battery, no loss of power-off data, no backup power supply for power-off data protection, protection time not less than 3 years

quantitative/batch control of measuring media (with start, stop and reset functions)

with two-way analog quantity transmission output

it supports RS485 and RS232 serial interfaces and adopts standard Modbus RTU communication protocol

the instrument can be equipped with RS232C printing function, with manual, timing and alarm printing functions

with DC24V feed output to power the field transmitter

photoelectric isolation technology is adopted among input, output, power supply and communication

the parameter setting password is locked, the parameter setting is permanently saved in case of power failure, and has the function of parameter restoration to factory settings

specifications and dimensions are type A, B and C wiring diagram

note: the wiring terminal directions of the rear cover of horizontal and vertical instruments are different, see diagram 1

1. In the selection of ③ and ④, if "X" is selected as the input graduation, it means that there is no compensation flow totalizer

2. Please select the function according to the wiring diagram during model selection, and apply a thin layer of MoS2 grease regularly; Regularly check the screws at the jaw and the instrument wiring terminals with small size can not bring full functions. For some functions, only one function can be selected on the same group of terminals

3. When writing the model, it must be complete. The unselected function items cannot be omitted and must be supplemented with "X"

example 1:nhr-5600a-27/x/x-0/x/2/x/x-a (no compensation)

example 2:nhr-5600a-27/27//x/2/d1/x-a (temperature and voltage compensation)

4. Only voltage or current signals are selected for the input type of pressure compensation channel; The input type of flow channel only selects voltage, current or pulse input, and pulse input is only selected for flow channel

5. If the vortex flowmeter needs to use the power distribution function, the second transmission output can be used as the power distribution function. At this time, the second transmission output is invalid

6. When the pulse signal is input, the instrument cannot select the second transmission output
