Product Introduction :
It is composed of three series 9988/818/TH freely, which is easy to realize the function of "what you see is what you get". Different combinations of various materials are suitable for most measurement conditions of pure liquid flow. Precise debugging before leaving the factory ensures the accuracy of the flow measurement as much as possible. Get more accurate flow measurement with minimal installation man-hours and minimal commissioning time available in the field.
Features:
1: Suitable for measuring pure liquid flow;
2: Applicable flow velocity range: 0.3-6m/s;
3: Applicable pipeline size range: DN15-DN50 (1/2-2");
4: Materials with broad chemical resistance;
5: Only the paddle-wheel and the shaft are moving parts, and the replacement steps are simple and fast;
6: One-piece delivery, saving on-site installation/commissioning time;
7: Precise calibration before leaving the factory to ensure accurate flow measurement;
Applications:
1: Chemical production process measurement; 2: Pure water preparation system;
3: Water monitoring;
4: Central air conditioning cooling cycle system
5: Electronic photovoltaic cleaning system
6: Metallurgical industry
7: Electricity, chlor-alkali industry
