CGZ-02B CGZ-01A INTELLIGENT CONVERTER

   CGZ-02B model electromagnetic flowconverter is adopted feedback signal enlarge processing method (the patent of China No.99113868.6) and mulit-CPU structure. The features and intelligential technology of converter arrives advanced international level.

Basic function
   ■ Max. dynamic rang: positive and verse flow measurement of 0.001~10 m/s
   ■ Accuracy: ±0.15% of measurement value
   ■ Repetitive error: +0.1% of measurement value
   ■ Response time: 0.1s~255s(selected)
   ■ Small signal cut: 0.001~0.5m/s(selected)
   ■ Accumulation method: absolute value of positive and verse flow, positive flow value, reverse flow value, algebra sum of positive and reverse flow value, select four accumulation methods
   ■ Exchange of volume and mass flow: in condition of flow density, to measure mass flow of fluid
   ■Obstruction set: display 0.5~99.9s (selected) , current output: 0.15~255s(selected)
   ■Exciting method & frequency: frequency is 50/2n positive and reverse rectangular wave, n=2~8(select)
   ■Diameter of transducer: 2.0～3000mm(set)
  ■Display method: figure and Chinese character display with backlight LCD. Positive and reverse instantaneous flow-rate display with max. 7 numbers (to select 1~3decimal), zero-elimination function. Max. accumulation flow-rate display is 10 numbers(include 3decimal) ,zero-elimination function. Six measurement combination display methods: accumulation/instantaneous, accumulation/percentage, accumulation/magnetic stick state pattern, instantaneous/percentage, instantaneous//magnetic stick state pattern, velocity/percentage.
   ■Timer: In operating, the timer works automatically and accumulates total time.
   ■Operation: manual operating with open cover and auto operating by magnetic stick
   ■Output: combined current, frequency and state output.RS-485 interface communication serial output
   ■Power: <10 W (exciting current: 60~120mA)
   ■Installation: integrated and separated type.

Intelligent function:
   ■Data display: select 11 measurement units(m?, l, ml, T, Kg, g, Gal, lb, SU, m, f) and 4 timing units(day, hr, min, s)
   ■Online data inquire: do not effect normal operation
   ■Self-examining function: self-examining & warning display function in case of empty tube, broken exciting cable, signal trouble and data setting trouble
   ■Operating and data self- protection: operating self-protection by softdog, lock modified data, data could be saved for 10 years in case of power-off.
   ■Auto-test and calibration; signal and current output calibration, exciting current test and adjust, and auto-zeroing function
   ■Ration control function; auto control function of input and output signal for accumulation ration value.
   ■Outside accumulation control function: control accumulation operation for converter by outside input signal, support calibration function for accumulation value.
   ■Intelligent key operation: function of keys displays automatically and operating by use of contactless magnetic stick

Input and output function
   ■Photo-isolation between all output signal and inside converter
   ■Analog signal output: Current: 0~23mA(select), resistance: 0~750Ω
Frequency: 0~1000Hz(select), pulse width from 0.5ms~999ms(select),
TTL level or OC output(select)
   ■Interface: RS-485 communication
   ■State position output: 8state positions of upper limit and lower limit, select high/low level and OC output
   ■Outside control input: current input control. Select accumulation control or ration control
