1 Product function
1.1 Feature and Usage
*Independence: When the temperature, pressure, viscosity and density of the measured fluid changing, the flowmeter will not be influenced.
*Easy Maintenance: No moving parts in measuring tube, so easy maintenance.
*Wide Application: Can measure conductivity liquid, without reference to fibre, solid or suspending material contained in liquid.
*Easy Installation: Install any angle only need liquid full of the pipe. Straight pipe requires 5D for upper stream and 2D for down stream.
*Turndown Ratio: The turndown ratio can reach to 1:100.
*Enclosure: For DN15~ DN1200 is IP68.
*High Intelligence: Back light English/Chinese LCD display, Menu setting control, three grades password protection, two-way measuring available, slight signal removal, Auto flow compensation and other function.
*SMT Technical: Intelligence self-detect and self-diagnoses, many kinds of alarming.
*SMART Excitation: Low power consumer, zero stability, longtime reliability.
*Multi-Signal Output: 4~20mA or 0~10mA current output, Standard Pulse Output, RS485 computer communication output.
Selecting the right lining and electrode material can measure nearly all conductive liquid.
The power supply system has good voltage vibration adaptability.
1.2 Special functions
- Power loss recording function; automatically logs the time of power loss, estimates un-recorded flows
- Total hour logging function; use recorded hours & recorded total flow to determine average usage
- Infrared hand-held remote control, program & use all display functions without opening the enclosure
2 Converter circuit block diagram
Fig. 2.1: Converter circuit block diagram
The converter circuit supplies a stable excitation current to the excitation coil in the electromagnetic flow sensor. The preamplifier takes the induced electromotive force from the sensor, amplifies it, and converts it into standard current or frequency signals which may in turn be used for displaying, controlling and regulating flow rates & totalized flows. A block diagram of the converter circuit is shown in Fig. 2.1
