For the new version meter, we update many functions.
1. velocity range: from 0.02-4.5m/s to 0.02-12m/s
2. level range: from 0-5m to 0-10m.
3. level measure: principle from only pressure to both ultrasonic and pressure measure.
4. new function: conductivity measure.
5. from analog Doppler to digital Doppler, the accuracy is better. from 2% to 1%R.
6. size is changed smaller and easier to install. the measured pipe Min. pipe size from DN200 to DN150.
7. added temperature compensation and pressure compensation function.
8. with bigger 4.5'' LCD display.
9. 6537 sensor can measure both forward and back flow, 6526 is only for forward flow.
10. with Epoxy-sealed body design instead of 6526 seal body.
11. Sensor with Modbus &SDI12 output instead of 6526 only with SDI12.
12. with an integral accelerometer sensor to measure the inclination of the sensor.
