NTK Floating Flowmeter Principle Usage!

2023-08-31 16:24:12

NTK is an abbreviation for NIHON TOKUSHU KEIKI (Japan Special Instruments), produced by the Japan Special Instruments Manufacturing Institute of the Corporation in Kashiba, Chiba Prefecture, Japan. Since its establishment in 1938, NTK Company has been specialized in designing and manufacturing various flow meter products, becoming a leading global brand in the field of flow meters.






NTK's main products include glass cone tube flow meters, metal tube float flow meters, constant flow valve float flow meters, mass flow meters, mass flow controllers, gas mixers, electric flow transmitters, flow indicators, flow indicator integrators, batch controllers, precision pressure reducing valves, back pressure valves, flow switches, and area flow meters. Shenzhen Oudejie Technology Co., Ltd. is also very concerned about the customer's demand for flow meter products and has been importing NTK flow meter products from Japan for a long time。


Introduction to the principle of NTK floating flow meter:


Floating flow meters have the simplest structure among variable area flow meters. It was invented by Chamery in 1858, and designed and patented by Karl Kruppers in 1910. The flowmeter has diagonal grooves engraved around the float, allowing it to rotate with the water flow. This type of instrument is called a rotameter because it was introduced to Japan in the 1920 version of T.R.K.


Place a float in the conical tube and install it vertically, allowing fluid to flow through the conical tube from bottom to top. A force is generated before and after the pressure difference float, pushing the float upwards. However, due to the increase in the annular area between the float and the conical tube, the flow rate decreases, and the pressure difference is equal to (P1-P2 is w/a) The float stops, and the scale of the stop position is the measured flow rate.




The main application areas of NTK floating flow meters are:


Floating flow meters can be used to measure the flow rate of two major types of media, liquid and gas. In terms of liquid media, such as measuring the discharge of wastewater treatment in the environmental protection industry, and measuring the flow rate of pipelines in chemical and metallurgical industries; In terms of gas media, such as energy metering, natural gas measurement, and environmental protection smoke emission measurement, etc. The specific classification is as follows:


1. Industrial production

2. Energy industry

3. Environmental protection industry

4. Biotechnology

5. Experimental Science


The above content introduces the principles and applications of NTK floating flow meters. In addition, Shenzhe ODJ Science & Technology Co., in selling new original imported NTK floating flow meters, and promises to sell all products with new original imports.
