LJZ-2 intelligent flow monitor is an intelligent digital instrument that uses single chip microcomputer as the core to process standard signals, it and three valve group The differential pressure transmitter and the like constitute a flow monitoring device, which constitutes a turbine volute flow monitoring system.
Second, the characteristics■ is a smart digital instrument with a single-chip processing system;■ transmitter range, instrument range setting and modification is simple;■ with breakpoint memory and parameter automatic protection function;■ instantaneous flow and cumulative flow can be switched display;■Alarm value can be set and adjusted conveniently;■Provide standard signal output corresponding to instantaneous flow rate;■Provide transmitter working power (+24V);■Use touch button, beautiful appearance.Third, technical parameters■ Power supply: AC220V ± 10% 50Hz■ Display range: instantaneous value: 0 ~ 9999 .99 m3 / S cumulative flow value: 0 ~ 99999999 Km3 measurement accuracy: ± 0.5% F. S1 word environmental conditions: Ambient temperature: 0°C~+50°C Relative humidity: ≤90%RH■Alarm setting: The alarm value can be continuously adjusted within the set range. When the monitored value reaches the alarm set value, the alarm relay contact operates simultaneously.Output: Analog quantity: DC4~20mA (load resistance≥525Ω)■Alarm contact output: Normally open two sets of contact capacity: 5A/AC220V or 5A/DC30V■Power: 12W
