Product Description

Ⅰ.Application:

The turbine flow meter is a kind of speed meter. It has high accuracy, good repeatability, simple structure, few active elements, wide measure range, small volume, light weight, low pressure loss. It also can easy to repair, and withstand voltage. So it can measure the volume flow and total quantity of the low viscosity of gas in the sealing pipe. It has wide application value in the petroleum, chemical, power plants, metallurgical and other industrial enterprises.
Ⅱ.Features:

1. It has wide measure range; the minimum velocity is less than 0.5m/s. The pressure loss is low, so the impeller can resist the impact.� �
2. It has higher electronic magnetic in EMI and higher anti-shake performance. Its working life is long and performance is reliable.

It adopts advanced the technique of Power down Single-Chip Microcomputer. The function of the whole body is strong, the power consumption is low, and the performance is advanced.

1. The meter factor can set on the line by the key, and it can be shown on the LED.
2. The meter adopts EEPROM, so it can protect the integrated flux and meter factor when the current is off.
3. It offers pressure compensation when the pressure of the measured gas is stable.
