Liquid Level Indicator - Product Reviews

Magnetic liquid level sensors pick up the slack where sight glasses fall short

Magnetic sensors have emerged as the preferred level sensor for applications where visual communication of liquid levels is crucial. Traditional level sensors consist of a float located inside a solid housing that communicates with an external indicator. Simple in design, it is not foolproof and plants are seeing its downfalls in certain applications. Colorless liquids are very difficult to see and breakable glass poses as a potential hazard if it cracks and spills hazardous materials.

Magnetic liquid gauges offer simple visual indication coupled with a transmitter that can deliver readouts from remote locations. As liquid levels rise the magnet-equipped float moves within the float chamber, and small magnets embedded in the flags rotate 180 deg to show its opposite side and color as it passes by. Magnetic sensors perform in high temperature, high pressure, and high vibration environment and many other applications requiring sturdy, high-quality design.

Best-in-Class Liquid Level Indicators feature:

  • Continuous-level digital transmitter for control or remote indication
  • Dependability in harsh environments and capabilities of high pressure and temperatures of at least 4200 PSIG and 750 degrees F
  • Add on switch capabilities for alarms and level control systems

Top Considerations before Buying Liquid Level Indicators:

For simple operation with long-lived accuracy ensure that the inside of the magnetic level indicator is transparent and hermetically-sealed. The indicator magnetically should float up and down inside the indicator tube with the rising and falling of liquid levels. Brightly colored indicators will allow the operator to read the level from 100 feet away. Consider only those designs that are capable of working within the required materials of construction that can function at the required accuracy and operating temperature.

Key Providers:

1. John C. Ernst Company Inc., founded in 1969, develops and specializes in process engineering equipment and devices for applications involving water, steam, oils, gases, chemicals, and sanitary projects. The company's produces flowmeter solutions for water, steam, acid, chemicals, air, gases, and high viscosity fluids. In addition to differential pressure flowmeters, other flowmeter devices can are dial type, digital with total and rate displays, shuttle type, variable area, and positive displacement oval gear type for high or varying viscosity fluids. Flow meters are available with 4-20mA transmitters, remote readout, pulse signals, can be field calibrated for fluids other than water, and can be battery operated when input power is not an option. We now have a Digital Flow Meter in PVDF Housing for aggressive chemicals. Additionally, the John C. Ernst Company manufactures and supplies observation equipment such as sight glasses, liquid level gauges, sight flow, illuminators, ejectors, and eductors for the petro-chemical, chemical processing, processing, food & beverage, dairy, pharmaceutical, semi-conductor, and boiler room equipment industries.

Bin Level Indication Applications in Cement Production and Concrete Batching Plants
BlueLevel Technologies, Inc.
Concrete is fundamental to our modern day construction and a key part of our global economy. Concrete is an artificial stone-like material used for various structural purposes. It is made from a mixture of water, cement and aggregates such as gravel, sand and stone, and then drying by hydration. Water and cement combine to be a “binder” and the aggregate, sand and gravel are the “filler” that is ...
