Main Features

1. LCD dot matrix display, Instant flow rate and totalized flow and temperature and pressure value can be displayed simultaneously with high-brightness backlight,simple and clear operation.

2. the dual probe technique can effectively improve the detection signal intensity and restrain the interference caused by pipeline vibration.

3. K-Factor linearity: XWAB provides 1 to 10 points k-Factor correction.

4. Adopting the leading real-time gain control and adaptive spectral filtering techniques the interference signals caused by vibration and pressure fluctuation are effectively suppressed.

5. It can be used in conjunction with vortex street, Precession Vortex, turbine,used for Piezo signal sensor and electric pulse signal sensor.

6. Easy to use: Only set several parameters by software or the device key, It can be used to measure the gas, liquid or steam of various instrument caliber.

7.HART with full-featured, including special commands.

8. the 16 bit microcomputer chip has the advantages of high integration, small size, good performance and strong function of the whole machine.No mechanical movable parts, stable and reliable, long life, long-term operation without special maintenance.

9. Intelligent flow meter flow probe, microprocessor, pressure and temperature sensor(Pt100or Pt1000) in one, take the built-in combination, make the structure more compact, can flow, pressure and temperature measurement of fluid directly, and real-time automatic tracking compensation and compression factor correction.

10. with EEPROM technology, the parameter setting is convenient and can be permanently saved, and the longest historical data can be saved for one year.

11. It has self checking function, rich self checking information, convenient for user to overhaul and debug.

12. with independent password settings, anti-theft function is reliable, parameters, total clearance and calibration can be set at different levels of passwords, user-friendly management;

13. the converter can output frequency pulse, 4 ~ 20mA analog signal, and has RS485 interface, can be directly connected with the microcomputer


14. the converter shows 360 degree rotation, and it is easy to install and use

15. the power consumption of the whole machine is low, the external power supply and battery power supply can be supplied, and the power supply mode can be switched automatically.

       Pulse output mode
A. Sensor pulse signal, pulse signal flow sensor, the isolated amplifier output, high level of more than 20V and the low level of less than 1V; frequency output, 0-5000HZ output, the corresponding instantaneous flow, this parameter can set the button
B. Equivalent pulse signal, the isolated amplifier output, high level of more than 20V and the low level is less than or equal to 1V, the unit volume can be set on behalf of the pulse range: 0.0001m3~100m3. Note: select the output equivalent pulse signal frequency is less than or equal to 1000Hz
 
   RS-485 communication (photoelectric isolation)
Using RS-485 interface, can be directly connected with the host computer or the two remote display table, medium temperature, pressure and standard volume flow and standard with temperature and pressure compensation after the total volume


       Correlation

4 ~ 20mA standard current signal (photoelectric isolation, HART communication) and the standard volume is proportional to the corresponding 4mA, 0 m3/h, 20 mA corresponding to the maximum standard volume (the value can be set at a level menu), standard: two wire or three wire, the flowmeter can automatically identify the inserted module according to the current correct and output
