Product Description:
The 818 series paddle-wheel flow sensor has reliable performance and optional integrated one-piece installation. Wide flow rate measurement, the sensor body material is PPH, PVDF, PFA optional, can withstand most of the current chemical corrosion. Paddle-wheel and shafts are durable and have been tested over a long period of time. The structure is simple, and it is an economical and practical choice. The probe signal transmission distance can be up to 400 meters.
Features:
1: Suitable for measuring pure liquid flow;
2: Applicable flow velocity range: 0.3-6m/s;
3: Applicable pipeline size range: DN15-DN400 (1/2-16");
4: Materials with broad chemical resistance;
5: The paddle-wheel/shaft is replaced quickly and conveniently;
6: Simple structure, few moving parts, long service life;
Applications:
1: Measurement of chemical production process;
2: Pure water preparation system;
3: Water monitoring;
4: Central air conditioning cooling cycle system
5: Electronic photovoltaic cleaning system
