Digital Indicating Intelligent Flow Totalizer Meter
Introduction
The 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...
Working conditions
1)Signal range: Impulse signal 0-99999P/L or 4-20mA output
2)Power supply of flow sensor: DC24V
3)Power supply of system: AC220V±10% 50Hz
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% (F·S
3)56×38 (mm) dot matrix backlight LED with English menu.
4)Functioned as batch flow control or flow display
5)Setting and independent trigger .for batch flow, switch 220VAC/6A
6)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.
