LU-50Y/51Y Flow Totalizer
The LU-50Y/51Y flow totalizer accepts flow signals from vortex, turbine, electromagnetic, Roots and other sensors. The flow channel supports frequency and analog current signals, the pressure channel accepts analog current signals, and the temperature channel is compatible with RTDs, thermocouples and analog current signals.
Selection customization and technical solution support available. After-sales Service 0086-400-8875-999, Pre-sales Hotline 0086-0592-5711111
The LU-50Y series flow totalizer and the LU-51Y series flow batch quantitative controller offer the following core features:
Accepts various flow sensor signals such as vortex, turbine, electromagnetic and Roots; the flow channel supports frequency and analog current signals, the pressure channel accepts analog current signals, and the temperature channel is compatible with RTDs, thermocouples and analog current signals.
Provides 24V power to transmitters, simplifying system design and reducing investment cost.
Fault-tolerant: when the temperature/pressure or density compensation signal is abnormal, the manually set value is automatically used for the calculation.
No potentiometers, coding switches or other adjustable components, resulting in higher shock resistance, stability and reliability, and it also provides extensive self-check and self-diagnosis functions.
Supports multiple communication modes and can form an energy metering network system with a host computer.
Performs high-accuracy compensation calculation for hot water, general gases, superheated steam, saturated steam and natural gas.
Provides daily/monthly/annual flow accumulation with permanent data retention after power failure; offers over-upper/upper/lower/over-lower limit alarms for instantaneous flow, temperature and pressure, and generates alarm records.
The LU-51YU quantitative controller supports batch control based on cumulative flow and can be operated by keys or external pushbuttons. It supports single-valve, large/small-valve and valve/pump batching, and allows the valve (pump) closing advance to be set.
