The Basics of Magnetostrictive Level Transmitters

Magnetostrictive level transmitters are continuous float level sensors that provide near real-time level measurements by creating competing magnetic fields to generate a signal corresponding to liquid level. Other types of continuous level sensors include radar transmitters, ultrasonic sensors, and submersible pressure transducers. Each of these has unique features that make them suitable or inappropriate for different applications.

Ultrasonic and Radar Level Sensors: Complementary, Not Competitive Technologies

Ultrasonic and radar level sensing technologies are usually described as competitors, pitted against each other, in a struggle for level-sensing supremacy. “Ultrasonic is better!” “Radar is the best!” The truth is that they are far more complementary than they are competitive, with each excelling in different situations. Anybody pitching either technology as a One-Tech-Fits-All level measurement solution isn’t telling the whole truth about the technologies and their products.

The Difference Between Ultrasonic and Radar Level Sensors

There is a tendency to pit ultrasonic level sensors and radar level sensors against one another when in reality each sensor has advantages and disadvantages that give each sensor its own place. In this blog, we will look at the differences in how these two technologies work and will cover the applications each sensor is best suited for.

Ultrasonic Level Sensor Used with Stilling Well in Water Level Sensing

This is necessary, especially with ultrasonic technology.

One such choice of alternate mounting is the use of a stilling well, as seen above with an MNU Ultrasonic Level Sensor, mounted under a manhole cover in a sewer application.

Ultrasonic Level Sensor Measures the Draft of Barges

Ultrasonic level sensor used to measure the draft of bargesAPG's object detection ultrasonic levels sensors are being used to measure the draft of barges in the waterways off the Louisiana cost.

The draft of a barge is the vertical distance between the waterline and bottom of the hull/keel. The draft determines the minimum depth of the water the barge can safely travel through. The barge draft can also be used in determining the weight of cargo which is calculated by the total displacement of the water caused by the barge.

Three Reasons the MNU IS Excels in a Variety of Applications

Physical Depth Measure and Solar Panel on Green Water TankIf you were to look up “versatile” in the dictionary, you might find a picture of APG’s new MNU IS Intrinsically Safe Modbus Ultrasonic Sensor. Ok, you might not yet, but you should, and soon. With features like APG’s new QuickMode, global Class I, Division 1 hazardous location certification, and RS-485/Modbus RTU standard on every unit, the new MNU IS is capable of handling just about any level measurement situation. Let’s take a look.

18 Programmable Settings You Need In An Ultrasonic Sensor

ultrasonic level sensor programmingLike anything else, there are both cheap and good quality ultrasonic sensors out there. Besides good manufacturing, one of the major differences between a good sensor and everything else is programmability. While non-configurable sensors might seem like a bargain, the advantages of programmable sensors add up to dependable readings and better control of your operation.

Since we can’t speak for all ultrasonic sensors on the market, let’s explore some of the benefits offered through our sensor’s programmable settings. Here are the 18 settings you can adjust in an APG ultrasonic sensor for optimal performance:

APG Introduces New Series MNU IS Intrinsically Safe Modbus Ultrasonic Level Sensor

MNU IS Intrinsically Safe Modbus Ultrasonic Level Sensor

LOGAN, UT – Automation Products Group, Inc. (APG) introduces a new ultrasonic level sensor, the Series MNU Is Intrinsically Safe Modbus Ultrasonic Level Sensor.

The MNU IS combines the flexibility and programmability of Modbus sensors with the ability to be installed in Class I Division 1 Hazardous locations. As with all of APG’s Tank Cloud compatible Modbus sensors, both the application parameters (Distance, Level, or Volume settings) and sensor performance parameters (Pulses, Signal Strength, Averaging, etc.) can be configured via APG Modbus software. And with certifications from CSA, IECEx, and ATEX, the Intrinsic Safety rating of the MNU IS is valid all around the globe.
