Detailed Description
GLW100 Flow sensor
flow transducer
1.The pressure loss is small
2.wide range, high precision
3.High reliability, small amount of maintenance
GLW100 flow sensor is mainly used in coal mine gas drainage pipe fluid flow measurement, such as gas, liquid and vapor, and other media.
Is characterized by small pressure loss, wide range, high accuracy, when the measurement is almost not affected by the fluid density, pressure, temperature, viscosity and other factors.
No moving mechanical parts, high reliability, small amount of maintenance. And the parameters of the instrument can be long-term stability. Vortex street flowmeter using piezoelectric stress sensor has high reliability, can be in - 20 ℃ ~ + 250 ℃ temperature inside the work.
Has a standard signal. Can also have a digital pulse signal output, and any monitoring system or other type system, is a more advanced, the ideal measuring instrument.
