flow totalizer

1. IntroductionThe flow totalizer and batch controller, fulfilling the receipt and process of impulse signal or 4-20mA via MCU technology, could simultaneously process and control the data and output via RS-232C interface. It is used as an intelligent meter for online measurement and control of flow... 2.

Working conditions.1) Signal range: Impulse signal 0-99999P/L or 4-20mA output2) Power supply of flow sensor: DC24V3) Power supply of system: AC220V±10% 50Hz 3.

Technical Specifications...1) This type could receive impulse signal or 4-20mA output and is able to display temporal flow, accumulated flow, accumulated mass and real clock.2) Tolerance of receipt of signal: ±0.5% ().3) 56×38 (mm) dot matrix backlight LCD with English menu.4) Functioned as batch flow control or flow display5) Setting and independent trigger for batch flow, switch 220VAC/6A6) Available RS-232C access to devices complied with the interface such like DY-301B in our company to print out measurement data...7) According to the temporal flow with 4-20mA input, output the correspondent current.

Resistance of the load is 750.8) Dimensions: frame dimension: 96×96 (mm), panel dimension: 91×91 (mm), depth: 100 (mm)9) Accumulated values of every parameters wont be lost even if power is off suddenly....
