Non-standard cables up to 150 total feet available on special order. Order Mounting Bracket for Sensor separately.   704U Digital Ultrasonic Level Controller by MJK The MJK 704U digital ultrasonic level controller is a microprocessor-based controller that works with MJK's rugged ultrasonic sensors for accurate level control. The ultrasonic sensors work best in applications where it is difficult for the sensors to be in contact with the fluid; it is not recommended for applications where fluid surfaces are rough or inconsistent. Select from the standard or PTFE-coated MJK Ultrasonic Sensors for the best performance in your applications. Program the four internal relays to control pumps, motors, valves, and alarms. The controller is supplied with seria ldata communication capabilities so that it can be connected to a SCADA system. Popular applications include water and wastewater pump stations and processing tanks, water towers and reservoirs, deep wells, lakes, rivers, and storage tanks. Features: Rugged ultrasonic non-contact sensor. Measures and indicates level, number of starts, pump run time; calculates capacity and output for each pump and total capacity for the whole pumping station. English or metric measurement units. Text display for programming and reading of measurement values with all indications in plain language (English or Spanish). 4 relays for control of pumps, valves, motors, and alarms. Lead/lag pump alteration. Serial data output for PC communication. Download 704 Product Sheet (.pdf; 309KB). Download 704 Applications Sheet (.pdf; 32.3KB).
