1. Nitrogen cabinet flow rate
5-25L/M or 5-60L/m. According to the different volumes of cabinets, nitrogen flow meters can be divided into 5-25L/M or 5-60L/m. The nitrogen cabinet is an oxygen concentration monitoring type nitrogen protection storage cabinet, suitable for storing finished products, semi-finished products, raw materials, and equipment during the production process of semi insulated conductor devices.
2. Characteristics and technical parameters of nitrogen flowmeter
The overall structure design of the instrument is reasonable, the dynamic measurement range is wide, and the pressure loss is small;
; The instrument body can be made of stainless steel material and is suitable for measuring skin sensitivity in corrosive media; The instrument has no movable parts and is easy to install and maintain; Output mode: on-site LCD display, pulse, 4-20mA output or 485 serial communication interface, can be connected to industrial automation systems; Power supply: built-in power supply (3.6V battery), external power supply (12VDC, 24VDC); Measure the maximum temperature of the collapsed abrasive material: 350 ℃; Working environment temperature: -30 ℃ to+55 ℃; (Pressure compensation at 0 ℃~+55 ℃) Working pressure1.6MPa~40MPa; Accuracy: Level 0.5, Level 1.0, Level 1.5. Nominal diameter: card type: DN10~DN300; Insertion type: DN350~DN1000; Group bucket flange type: DN10~DN300.
3. What is the price of an external clamp ultrasonic gas flowmeter?
The price of 140000 yuan for the external clamp type is a bit expensive. Without so much, there should be a missing decimal point in the middle, I feel.
4. How much does a vortex flowmeter with TS certificate cost? To underst
and these points, the price of vortex flowmeters with TS certificates cannot be directly determined. It needs to be determined based on specific selection and comprehensive evaluation of operating parameters. The following are the key factors and selection suggestions that affect prices: Measurement media and operating parameters. The measurement media of vortex flowmeters include steam, compressed air, nitrogen, carbon dioxide, mixed gases, and liquids. The density, viscosity, and other characteristics of different media will affect sensor selection and material costs. At the same time, it is necessary to clarify parameters such as pressure, temperature, and flow range. For example, special materials (such as stainless steel) and sealing structures are required for high-temperature and high-pressure working conditions, which significantly increases costs. Taking the LUB series as an example, it supports DN15-DN500 caliber with an accuracy level of 1.0, but the specific model needs to be matched according to parameters such as medium flow rate and pipeline size. Image: LUB series vortex flowmeter supports multi-media measurement function configuration requirements. Anti vibration performance: If there is mechanical vibration in the working condition (such as near the pump room or compressor), a model equipped with DSP signal processing circuit and anti vibration algorithm should be selected to ensure stability by shielding interference signals. This type of technology will increase costs. Explosion proof performance: In flammable and explosive environments (such as chemical and oil and gas fields), explosion-proof flow meters should be selected and certified with explosion-proof certificates.
