Feature
The vortex flowmeter is mainly used in petroleum, chemical engineering, metallurgy, power, and heating industries and is used for liquid, air, and steam flow measurement and detection control in closed pipelines of municipal construction and environmental protection projects. It is capable of outputting impulse frequency signals or (4 ~20)mA standard current signals. If matched with an appropriate industrial automation instrument, it can display instantaneous and accumulated flow rates, and implement multiple functions such as flow measurement and automatic control. Besides, the vortex flowmeter features a wide measuring range, high precision, and low-pressure loss... It can be used to measure specific working conditions and volume flow rates. Moreover, such measurement is hardly affected by relevant physical parameters, including fluid density, pressure, temperature, and viscosity. Instrument coefficients are highly reliable and remain stable in the long term. Almost no maintenance is required.

Application description
Rebar is the common name for hot rolled ribbed steel bars. The grade of ordinary hot-rolled steel bar is composed of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words Hotrolled, Ribbed, and Bars respectively. Hot-rolled ribbed steel bars are divided into three grades: Grade II HRB335 (the old grade is 20MnSi), Grade III HRB400 (the old grades are 20MnSiV, 20MnSiNb, 20Mnti), and Grade IV HRB500.
