Electromagnetic flow meter application classification
[email protected] Electromagnetic flow meter flow transmitter is an instrument that measures the flow rate of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. The product is mainly used to measure the volume flow in conductive liquids and slurries in closed pipelines, including highly corrosive liquids such as acids, alkalis, and salts.

Thermal Gas Flow Meter
[email protected] The thermal gas flowmeter is designed according to the principle of thermal diffusion, and the instrument uses the constant temperature difference method to accurately measure the gas. It has the advantages of small size, high degree of digitization, convenient installation and accurate measurement. Technical advantages 1. The gas flow measurement of the real mass flow meter does not require temperature and pressure compensation, and the measurement is convenient and accurate. available gas Body weight flow or standard volume flow. 2. The thermal gas flow meter has a wide range ratio, can measure gas with a flow rate as high as 120Nm/s and as low as 0.1Nm/s, and can be used for gas leak detection. 3. Compared with general measuring equipment, Kunke thermal gas flowmeter has good shock resistance and long service life. The sensor has no moving parts and pressure sensing parts, and is not affected by vibration on measurement accuracy.

Adhesive glue metering pump
Professional Metering Adhesive Glue Gear Metering Pump The biggest problem faced by adhesive users is whether the spray can be even. Reciprocating pumps, such as diaphragm or plunger pumps, generate fluid flow that varies in both pressure and flow. To make up for this, it is necessary to fully spray the target area with more adhesive. Excessive spraying will lead to additional waste of materials and increase manufacturing costs.

oil extraction flow meter
[email protected] In oil extraction, different flowmeters will be used according to the actual situation, so today I will introduce the working principle and characteristics of oilfield flow meters 1. Velocity flowmeter. The flow meter that directly measures the liquid flow rate of the full pipe flow in a closed pipe through various physical phenomena, and further calculates the flow rate is a velocity flow meter. It mainly includes turbine flow meter, vortex flow meter, ultrasonic flowmeter, etc. It is characterized by high precision (up to 0.5 grade)

Vortex flow meter to measure steam mass flow
The vortex flowmeter is a volume flowmeter, that is, the fluid Reynolds number is within a certain range, and its output is only proportional to the volume flow. The output of the vortex flowmeter has a frequency signal and an analog signal, and the analog output is obtained by f/I conversion on the basis of the frequency output. There is about a 0.1% loss of accuracy in this conversion. Therefore, when used to measure steam flow, users prefer to use frequency output. 1 Several other reasons why the frequency output vortex flowmeter is more popular with users such as heating companies are as follows.

How to choose electrodes for magnetic flow meter
There are many types of electrodes for electromagnetic flowmeters. The conventional ones are 316L, Hastelloy, titanium, tantalum, platinum-iridium alloy and so on. So here, Shanghai JSN Instrument Co., Ltd. will share with you the tips for selecting electrodes: As long as it is used to measure water, choose 316L electrode, which is economical and affordable; As long as the medium contains a certain amount of acid and alkali, instead of hydrofluoric acid, oleum and alkali, then choose a tantalum electrode, which can withstand the corrosion of most chemical media.
