TV815L throwing-in liquid level transmitter



TV815 is two-wire system , static pressure liquid level transmitter. It uses imported silicon piezoresistive sensor which has featured as high performance and reliability, matched with special integrated circuit and strict process flow, is strong in anti-overload, high precision and reliability. TV815 has multiple protection to prevent surge voltage, RF interference, over-voltage, reverse power protection to insure the high reliability. TV815 can be widely used for unsealed fields or open containers. For example dams, power generation plants, high-rise towers, cooling towers, wastewater tanks, pumping stations, water factories, hydrogeololgy, petrochemical, stream surveillance, and so on.
