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.

APG Introduces the new MPX-E Chemical Magnetostrictive Float Level Transmitter

APG's New MPX-E Chemical

LOGAN, UT – Automation Products Group, Inc. (APG) introduces a new float level transmitter, the MPX-E Chemical Magnetostrictive Float Level Transmitter with a chemical resistant coating.

The corrosion resistant MPX-E Chemical brings you accurate and dependable level measurements in places where stainless steel doesn't measure up. The chemical resistant coating is designed for use in corrosive, acidic, and marine environments, such as: sulfuric acid, boric acid, hydrochloric acid, sodium hydroxide, and sea salt water.

Myth Busted: Floats Don’t Stick On Continuous Float Level Transmitters

continuous float level transmitters use buoyancy to measure levelSometimes we develop myths about certain technologies. None are more frustrating than the belief that floats on continuous float level sensors get stuck.

We like to get as much industry feedback as we can. Trade shows are a good opportunity to do this. Over the last several years attending OTC in Houston, many have told us that they resist using float level transmitters, or magnetic level probes, because they’re worried the float will get stuck.

So we decided to debunk the myth here. Bottom line, we have 10,000 + units in the field (most from long time customers), in anything from Wastewater lift stations to Oil and Gas mud tanks, and the floats never get stuck.

That’s not to say it isn’t possible, but in the applications where this sensor technology works well, it just isn’t happening. This is due to three important factors:

Level Transmitter Vs. Harsh Environment: Winning The Battle

Getting the right level transmitter for the job doesn't come with a trophy, but it feels great

A level transmitter's job is a little harder than you may think. Sure, the concept of detecting a liquid level and transmitting a signal to a control system is pretty simple. However, the concept leaves out all the sticky specifics.

The problem is that we often put our level sensors in - and this is saying it nicely - harsh environments.

Defining Harsh

The term "harsh" is a pretty broad one. An environment can be called "harsh" if it is:

What It Takes to Install a Magnetic Tank Gauge

Installing a magnetic tank gauge can be easy with the right equipmentCall it what you want, a magnetic level sensor, a stem sensor, a float, or even a stick level sensor, when you decide to use one, you need to understand the installation requirements to make things go quickly and smoothly.

The primary concern for installing a magnetic level sensor is the mounting, as wiring is simple and consistent. Mounting can be very easy, even for a sensor with a very long stem, as long as you have the right equipment. For example, a 20 ft. long sensor will likely require a few hands on deck, and perhaps a lift – such as some scissor lifts or a cherry picker.

When to Use a Float Switch and Point Level Sensor

Custom multi-point float switchesFloat switches, and other point level sensors, are great alternatives to the more expensive continuous level sensors (ultrasonic, radar, level probes, etc.). Functionally, of course, they are not as capable. However, they work great under the right circumstances and continue to be a staple in level measurement applications throughout the world.

When To Use

The right time to use a float switch is tied to the application goals. What does the sensor need to do? If the answer to that question...

Continuous Level Control for Pumping Stations

Many businesses and municipalities are using continuous level sensors. Some popular sensors for continuous level measurement are submersible pressure transducers, ultrasonic and radar sensors, and level probes.
