LCW micro flow sensor
Product
Product Introduction
Type LCW micro flow sensor are instrument used for the continuous and intermittent measurement and control of pipe liquid flow. Which are typical of feature large flow range, low pressure loss, large viscosity range, easy installation, high accuracy, and can measure high temperature, high viscosity liquid with easy calibration. The meter are widely used for the flow measurement in the field of petroleum, chemical, chemical fiber, traffic, boats and ships, food industries and commerce, medical and sanitary departments.
The micro flow sensor is generally comprised of a flow transducer and a counter. The main part of the transducers a measuring chamber which consists of a part of oval wheels and cover plate and the walls of measuring chamber. The counter contains speed reduction gears, adjusting device, counter, and pulse transmitters etc.
The counter has mechanism and electron two kinds of type of counter, if the flow transducer is collocated the mechanical counter, the total liquid volume will be known by the pointer display and the roller number, the attached signal generator produces the pulse signal, and then transmitters it to the electrical indicator to display total liquid volume and instantaneous flow and control, if the flow transducer is collocated the electronic counter, the total liquid volume and instantaneous flow will be known directly.
STRUCTURE AND OPERATION PRINCIPAL.
In the measuring chamber, a part of oval wheels and cover plate make a fan shape cavity which is used as a measuring element. The oval wheels are rotated by the little pressure difference in the inlet and outlet of the meter and drive the inlet liquid through the cavity to the outlet, each revolution of the oval wheels displaces fluid four times the volume of cavity, the total revolutions of the oval wheels and revolutions rate will be transferred to the counter.

Installation
(1)A filter should be installed in front of the meter, and be sure that the arrow on the casting of the meter and filter pointing the same direction of the liquid flow.
(2)Whether the pipe line is vertically or horizontally installed, the wheel’s shaft of the meter must be fixed horizontal, that is, the dial is vertical the surface.
(3)Pipes to the installation of the meter, the pipe must be cleaned.
(4)While the meter is installed properly, the counter may be turned 180° or 90° for easy reading.
(5)A regulating valve must be fixed at the of the meter, a shutoff valve at the outlet, the valve must be slowly opened to prevent from a sudden impact, and water hammer.
(6)It is forbidden to clean the meter with steam.
(7)For the continuous operating department, a bypass should be mounted.
(8)The filter should be cleaned out of impurity to prevent from blocking, the meter should be tested and overhauled in a fixed period.
