Sensor ROLA
1.description
A level sensor (hydrostatic level gauge/level transmitter/level
sensor/water level sensor) is a pressure sensor for measuring
liquid levels. The static pressure input liquid level transmitter (liquid level
meter) is based on the principle that the measured hydrostatic
pressure is proportional to the height of the liquid. It uses
isolated diffused silicon sensitive element or ceramic capacitive
pressure sensitive sensor to convert the static pressure into
electrical signal, and then converts it into standard electrical
signal (generally 4 ~ 20mA/1 ~ 5VDC) after temperature compensation
and linear correction. It is suitable for liquid level measurement of various media in
petrochemical, metallurgy, electric power, pharmaceutical, water
supply and drainage, environmental protection and other systems and
industries.
2. System Summarize
The “Liquid height measuring system in GPRS communicate mode”
include “Liquid height measuring terminal equipment in GPRS
communicate mode”, “Server Management Software” and “Configuration
Line”. It is used for timing measure liquid height value,
temperature value, longitude and latitude data, date and time
information and show these value in the “Server Management
Software”.
Notice 1: The “Liquid height measuring system in GPRS communicate
mode” for short “System” as following description.
Notice 2: The “Liquid height measuring terminal equipment in GPRS
communicate mode” for short “Terminal” as following description.
Notice 3: The “Server Management Software” for short “Software” as
following description.
Notice 4: The “Configuration Line” for short “Line” as following
description.
The “Terminal” is used for timing measure liquid height value and
temperature value, and transmit these measuring value to the
“Software” in GPRS communicate mode, the user can use “Software” to
see the liquid height value and manage these “Terminal”.
The “Software” is only a demo software to offer the user, its
function is very simple, and it is not have a powerful function to
take many “Terminal” running at the same time. If user need a large
system “Software” with powerful function, please contact Xi’an
Kacise Optronics Tech Co., Ltd.
The “Line” is only used for configure “Terminal” by user, it is
connect between the “Terminal” and the RS232 serial port of
computer.
