The ultrasonic flow meter utilizes the principle of low voltage and multi-pulse time difference, adopts high-precision and ultra-stable
double-balanced signal differential transmission and differential reception digital detection technology to measure the acoustic wave
transmission time in the upstream and downstream directions , and calculates the flow rate according to the time difference.
Ultrasonic flow meter has the characteristics of good stability, small zero drift, high measurement accuracy, wide range ratio and strong
anti-interference.

Today, i will introduce the working principle of gear dosing metering pump to you.
The gear metering pump is driven by a pair of intermeshing gears, one of which is a driving gear and the other is a passive gear, which is driven
by the driving gear to mesh and rotate. There is a small gap between the gear and the casing of the pump. When the gear rotates, in the
suction chamber where the gear teeth gradually disengage, the closed volume between the teeth increases, forming a partial vacuum, and the
liquid is sucked into the suction chamber under the action of the pressure difference. It is pushed forward by the gear between it and the
casing, and sent to the liquid discharge chamber. In the liquid discharge chamber, the two gears are gradually meshed, the volume is reduced,
and the liquid between the gears is squeezed to the liquid discharge port.
Because the machining accuracy of the gear metering pump is very high, whether it is the tooth surface accuracy of the gear, or the matching
accuracy of the gear and the casing, the gear and the tooth top are very high, so the gear metering pump has a certain rotational displacement.
In other words, every time the gear rotates, the volume of the liquid discharged is constant, so as the speed of the gear metering pump is
adjusted, the gear metering pump can discharge a corresponding amount of liquid.

Before using the magnetic flow meter, we need to understand two settings about this flowmeter. The first is the wiring method of the
flowmeter; the second is how to adjust the flow rate.
The wiring method of electromagnetic flow meter:
When the electromagnetic flowmeter uses cable wiring, in order to prevent rainwater from penetrating into the sensor, when entering the
electrical interface of the sensor, it is necessary to make a U shape at the port. If the excitation cable is used, the Yz medium-sized
rubber-sheathed cable can be used, and its length is the same as that of the signal cable; if it is installed separately, the connected signal
cable adopts a customized special cable, and the shorter the cable, the better. At the same time, it should be noted that the signal cable must
not be laid in the same pipe with other power sources, and must be strictly separated. It cannot be twisted together and should be placed in
the steel pipe separately, and cannot be laid equally. When wiring, it is recommended that the excitation cable and the signal cable be as short
as possible, and the redundant cables should not be rolled together. The redundant cables should be cut off and the joints should be re-soldered.

JSN micro oval gear flow meters are widely used in the spraying industry, automotive painting, and motor coil painting. The spray paint industry
is a typical application for accurate monitoring of spray detection quantities.
The problem encountered by the customer at the site is that the varnish will be cut off when the flow is cut off, which will cause the rotor to not
be varnished (the varnish is transparent), and the coating amount is relatively small, so it is not easy for workers to find such a situation. This will
cause the produced rotor coil to enter the product assembly in a state without varnish coating. However, when the rotor is working, it will wear
back and forth, causing the coil to be scrapped, resulting in scrapped products and affecting the reputation of the manufacturer.
Shanghai JSN Micro Flow Meter CO.,LTD as a high-tech industrial products manufacturing and complete sets of product sales, R & D, production, processing and sales as one, with independent import and export rights of enterprises.
The company's main flow meter, level meter, and pressure controller, temperature controller, analytical instruments and other various types of instrumentation. To solve all kinds of problems, and provide complete sales service for customers with professional technical point of view.
