1. The advantages of using a plate hole and differential pressure transmitter to measure flow rate... why not directly use a flow meter?

By using differential pressure to measure flow rate, non-contact measurement can be achieved by sealing the pressure tube with silicone oil - that is, the sensor does not directly contact the medium, but measures through pressure conduction. Only the orifice plate and pressure interface are in contact with the medium. This measurement can be used for almost any fluid with good fluidity, as the orifice plate and interface are easy to achieve regardless of the material used.. If other flow meters are used for measurement and the medium has special variations, then it is necessary to directly customize the sensor, which is costly and difficult for the manufacturer to produce. In addition, if the density and performance characteristics of the medium change, compensating with a differential pressure flowmeter can be easily achieved, while using other flowmeters requires recalibration before use, which is very inconvenient for users. Using an electromagnetic flowmeter, if the medium is suddenly replaced with a non-conductive medium, the electromagnetic flowmeter may not even be usable.

2. What equipment is required for the production of water-soluble silicone oil?

The core equipment for producing water-soluble silicone oil is a reaction kettle with stirring and temperature control, combined with a condenser and vacuum system to complete synthesis and purification.

. 1. Core reaction module equipment: The reaction kettle is the core equipment, usually made of 304 or 316L stainless steel, equipped with heating/cooling jackets, anchor or frame mixers, and capab

le of accurately controlling temperature and vacuum degree. Its capacity varies from several hundred liters to several tons depending on the production scale. 2. Auxiliary process equipment: Condensers are often used in a tubular manner to condense the steam generated by reflux reactions and improve raw material utilization. Vacuum system: composed of vacuum pumps (such as water ring pumps, rotary vane pumps) and buffer tanks, used to remove low boiling materials or water in the reaction and create vacuum reaction conditions. Measurement equipment: including electronic scales, flow meters, etc., used to accurately control the feeding ratio of main raw materials such as silane and polyether, as well as catalysts. Filtering equipment: such as plate and frame filters or bag filters, used to filter out solid impurities such as catalyst residues after the reaction is completed, ensuring product clarity. Storage and matching of raw materials and finished product storage tanks: They should be made of stainless steel material with nitrogen protective sealing covers to prevent material moisture absorption or oxidation. Conveyor system: Diaphragm pumps or gear pumps are used to transfer materials between various equipment. Control system: Contemporary production equipment typically integrates PLC or DCS automated fiber control systems to achieve centralized monitoring and recording of key parameters such as temperature, pressure, mixing speed, and material flow rate.

3. Typical applications of target flow meters

Gas types: coal gas, air, hydrogen, natural gas, nitrogen, liquefied petroleum gas, hydrogen peroxide, flue gas, methane, butane, chlorine gas, mixed gas, etc.
