What Should You Look for In Your Liquid Level Measuring Device?

If you need to regularly monitor liquid levels in your place of business, you know how tedious the process can be if you don’t have the right tool for the job. Your delicate operation can’t handle an invasive process that leads to issues with your production. You need to find a device that can measure all the liquids that you need unobtrusively. There are a variety of devices that you can use for this process, and it’s important to choose the one that suits your process best.


First and foremost, you’ll want to look into an ultrasonic device. They’re the most common and popular type of continuous level sensor for a very good reason. This continuous level sensor uses sound waves bounced off the water to read the water level as accurately as possible. It’s very effective and efficient and allows for minimal disturbance of the process. It has very few downsides, but one of them is that it does not work properly in a vacuum. This won’t affect most jobs, but it may be relevant to your specific needs. If your business needs a continuous level sensor, then you can do a lot worse than the ultrasonic variety.

Free Space Radar

This is another kind of liquid detection sensor, and it’s one that may fit your business needs. This product shoots a radio wave into the liquid, and it measures the change in the wave to determine the level of the liquid. This method is quite accurate and can work in a vacuum. It’s also not easily affected by changes in temperature. However, it struggles with condensation, and foam can block the signal entirely in unfortunate situations. This is another great option for a liquid detection sensor.

Guided Wave Radar

This liquid detection sensor works very similarly to the previous one. However, it is able to bypass any issues caused by condensation or dust, making it more accurate than the free space radar. As far as a continuous liquid level sensor goes, this is one of the more powerful options. However, it is more difficult to install than one of the other kinds of sensors. If you want a continuous liquid level sensor with maximum accuracy, this is one of the better options that you have at your disposal.

Different Methods to Measure Fluid Levels

When you need to measure fluid levels, you have a few choices in front of you. Make sure that you’re fully aware of all of your options when you decide to purchase your non-invasive flow meter. You’ll want to know what each kind of meter is capable of so you know which one best suits the needs of your business. You don’t want to end up with a meter that doesn’t get the job done and end up frustrated.

Continuous Float Level Transmitters

This kind of fluid level sensor functions somewhat similarly to the dipstick on your car. The tip goes into the water and sends vibrations up the rod that indicate where the water is at. This is a simple but effective fluid level sensor that can get the job done without too much fuss. This is a great choice if you’re looking to handle your fluid level sensor needs as easily as possible.

Differential Pressure Transmitter

This fluid detection sensor detects the pressure at the high and low end and transmits the data back to determine the fluid level. It’s a great way to make sure that you’re getting an accurate reading without an overly complicated device.

Load Cell

This type of fluid detection sensor measures weight to give accurate readings on the fluid level in the object. There are a wide variety of the cells, from the cheaper mass-produced type to the custom-designed kind, that can give even more accurate readouts.

Radar Level Transmitters

This noninvasive flow meter is the perfect way to measure the fluid level without interfering with it directly. There are times when you don’t want to make direct contact with the water in order to measure it, and this is the perfect way to get those accurate measurements that you need without disturbing the liquid in any way. It requires more effort to set up than other methods, but it’s worth it for the accurate measurements. One of the weaknesses of this type of non-invasive flow meter is the fact that it’s not very portable.


This kind of sensor is very simple and straightforward to use. It uses ultrasonic waves to detect the fluid level without ever interfering with the liquid itself. This is one of the easiest and best ways to get these measurements, and it’s one that you should seriously consider for your business.

To Summarize

There is a wide variety of options for measuring fluid levels out there. It’s easy to see why when each of them has such different methodologies. Whatever your needs are, you should visit the Introtek website to learn more about this and other products.

Critical Sensors for Hemodialysis

The kidneys are responsible for filtering and removing waste products from the blood. Hemodialysis is used for those with severe kidney disease to aid their filtering process. Blood is pumped out of the body and into the machine, where it passes through a network of small filtering tubes that simulate a human kidney.

A number of critical sensors are required for hemodialysis to be effective, including the blood leak detector. Different sensors are required for accurate monitoring of liquid flow, pressure, and temperature in both the patient’s blood and the circulating dialysate. They also allow for rapid detection of air bubbles present in either of the fluids.

Principles of Hemodialysis: Mechanical and Safety Monitors

The non-invasive blood leak detector is a key component of many modern-day hemodialysis machines. It functions to detect minute amounts of blood in clear fluids on plastic tubing to identify any blood leaks in the dialasyste line.

This mini blood component detector uses a light source with an optimum wavelength. If the blood traveling through the tubing of the dialysis machine exceeds this threshold, an alarm is triggered. This optical-based system is important to identify unwanted elements in the blood or dialysate to ensure maximum safety during hemodialysis.

Waste materials and fluid are able to pass through the membranes of the tubing into the dialysate, a clear fluid that flows in the opposite direction on the outside of the tubes. The filtered blood then travels back into the body.

Although complications with dialysis are rare, the blood leak detector is a major safety mechanism that every dialyzer machine requires. When small fractures of blood are present in the dialysate, it indicates a small membrane rupture in one of the tubes. This can be life-threatening to the patient, as a contaminated fluid may come into contact with the circulating blood.

The safety of dialyzers can be attributed to the incredible critical sensors and detectors that ensure the blood and dialysate are kept apart at all times. Contact Introtek to learn more.

The Evolution of the Level Sensors Industry

From healthcare and pharmaceutics to food and beverage, a number of different industries use level sensors to control and manage their operations. A liquid level sensor, for example, can be used by companies within these industries to monitor and regulate the volume and flow of liquids in a specific contained space or through an open system.

There are two measurements that are taken with these sensors. A continuous level sensor, for instance, accurately measures the liquid levels from a plastic tube or container in a non-invasive manner. It also monitors the levels of fluid within a specific range to produce an analog output that correlates to the liquid levels in the container. Point level measurements, on the other hand, detect the fluid levels to mark a predetermined single liquid height that provides additional information about the fluid level within the container.

The use of these sophisticated level sensors is integral to several industries:


  • Sensors can be used to minimize wastage during manufacturing processes to reduce losses in time and resources while increasing work efficiency.

Food and Beverage

  • The liquid detection sensor can be effective in measuring liquids and semi-liquids in food and beverage production.

Healthcare and Pharmaceutics

  • Drug manufacturing requires a high level of specificity and accuracy to ensure the safety of consumers. Level sensors have been critical to this process for years. They can be used to monitor specific liquid levels in drugs, which is key to formulating medications with the correct concentrations.
  • Sensors are also critical to the function of a number of medical devices, including dialysis machines. Both the blood and the dialysate are closely monitored via non-invasive liquid sensors to identify potentially life-threatening leakages in the system.
