KH-LC series of mechanical flow meter is used for fluid flow in the pipeline for continuous measurement of high-precision flow meters, oval gear flow meter with a measurement range of large and small pressure loss, strong viscosity adaptability advantages. Widely used in the accurate measurement of petroleum, chemical industry, metallurgy, food, medicine, business and other sectors of liquid pipelines. Works under the action of liquid pressure at both ends of the measuring chamber and export of instruments, a pair of oval gear gyrate and discharge of liquid on the shaft, the measured number of revolutions oval gear can know the total value of the liquid flowing through the meter. The main technical parameters of the basic error limit: ± 0.5% Operating temperature: -10 to 60; 60 to 120 Nominal pressure: 1.6MPa; 2.5MPa; 3.2MPa pressure loss: 0.1MPa (in 5-15MPa · s viscosity within the range of the measured liquid pressure loss at maximum flow) Liquid Viscosity: 1-300MPa · s precision coefficient: 0.5, 0.2 technical data of ordinary cast iron type (a), steel type (e), stainless steel type (b) Model KH-LC LC- a cast iron LC-e stainless steel LC-b Nominal Mpa 1.0 1.6 2.5 4.0 6.4 1.0 1.6 measured liquid viscosity 2 ~ 200 Mpa.s measured liquid temperature -20 ℃ ~ + 100 ℃ flow range m3 / h model KH- LC accuracy class KH LC-a cast KHLC-e KH LC-b stainless steel nominal diameter (mm) 0.5 0.2 0.5 0.2 0.5 0.2 10 0.04 ~ 0.4 0.1 ~ 0.4 0.04 ~ 0.4 0.1 ~ 0.4 0.1 ~ 0.5 0.1 ~ 0.5 15 0.25 ~ 1.5 0.3 ~ 1.5 0.25 ~ 1.5 0.3 ~ 1.5 0.3 ~ 1.5 0.3 ~ 1.5 20 ~ 3 0.6 ~ 0.5 0.5 ~ 3 0.6 ~ 3 3 3 0.6 ~ 0.6 ~ 3251 ~ 1.2 ~ 61 6 ~ 6 ~ 6 1.2 1.2 ~ 6 ~ 640 2.5 ~ 1.2 153 ~ 15 2.5 ~ 15 3 ~ 15 3 ~ 15 3 ~ 15 504 ~ 24 244 ~ 24 4.8 ~ 4.8 24 ~ 24 4.8 ~ 4.8 ~ 24 655 ~ 408 ~ 40 5 ~ 408 ~ 408 ~ 408 ~ 408 010 ~ 6012 ~ 6010 ~ 6012 ~ 6012 ~ 6012 ~ 6010016 ~ 100 20 ~ 100 16 ~ 100 20 ~ 100 20 ~ 100 20 ~ 100 15032 ~ 19038 ~ 19032 ~ 19038 ~ 19038 ~ 19038 ~ 19020034 ~ 34068 ~ 34034 ~ 34068 ~ 34068 ~ 34068 ~ 340
