Introduction of single flange and double flange differential pressure level gauge
In the process of industrial production and manufacturing, some of the tanks measured are easy to crystallize, highly viscous, extremely corrosive, and easy to solidify. Single and double flange differential pressure transmitters are often used in these occasions. , Such as: tanks, towers, kettle...Read more -
Types of pressure transmitters
Simple self-introduction of pressure transmitter As a pressure sensor whose output is a standard signal, a pressure transmitter is an instrument that accepts a pressure variable and converts it into a standard output signal in proportion. It can convert the physical pressure parameters of gas, li...Read more -
Radar Level Gauge·Three Typical Installation Mistakes
Advantages in the use of radar 1. Continuous and accurate measurement: Because the radar level gauge is not in contact with the measured medium, and it is very little affected by temperature, pressure, gas, etc. 2. Convenient maintenance and simple operation: The radar level gauge has fault alar...Read more -
Introduction of Dissolved oxygen meter
Dissolved oxygen refers to the amount of oxygen dissolved in water, usually recorded as DO, expressed in milligrams of oxygen per liter of water (in mg/L or ppm). Some organic compounds are biodegraded under the action of aerobic bacteria, which consumes the dissolved oxygen in the water, and th...Read more -
