Detailed Description
ew TR - 100W batteries type ultrasonic industrial water use has 50 db dynamic range of receiving amplifiers, optional external clip, insert, pipe sections, the original sensor etc. Product small flow drift Compared with water and mechanical parts, the activities of tumor-initiating low flow, range is wide, high accuracy, and long service life etc. Technical parameters: * measurement precision, better repeatability: 2%, than 0.5% Power supply: 3.6 * work 19AH V/li-ion battery voltage power supply (p) when the normal work 2.6 V * measurement cycle: 500ms ~ 49 seconds (factory default 10 seconds) * number of samples: each measurement cycle number of samples and group ~ 128 group optional (factory default 64) * show: local 96 segment LCD display, it can display different content of 44 window Operation: use special * secondary instrument or PC set and software download sites (company), by RS485 parameters, can browse 44 window contents * optional output: so 1 road USART (TTL) output So one way RS485 output (optional internal or external lithium battery power dc power supply), OCT. So isolated output (pulse width 1000ms 6 ~ between programmable, default 200ms) so 1 road two-way serial peripherals, can directly through a generic interface to connect multiple forms of series equipment: 4-20 ma analog output signal output, frequency, thermal printers etc (external power supply, and is not recommended for use, if the proposal chooses one-piece flowmeter) * optional input: two road PT1000 platinic resistance MODBUS: * communication protocol agreement, M - BUS protocols, FUJI, and expand agreement of similar products of other manufacturers compatible domestic communications protocols Other functions: so * 512 days before the automatic memory, first 128 month 10 years before, positive/negative/net accumulated flow so automatic memory before 30 times, time and flow and power can be realized automatically or manually add, and can be read by MODBUS agreement So can be transmitted via E-mail to realize the code file software upgrades IP68: * protection grade Length: with ordinary pipe *, direct mechanical meter change installation
