Why Ultrasonic Level Sensor and Ultrasonic Level Transmitter Are Essential for Liquid Control

Precise regulation of liquid level is a basic requirement for all industry—chemical processing to water supply. Among various technologies employed, ultrasonic level sensors and ultrasonic level transmitter are the most accurate, reliable, and convenient technologies employed. The first among them is the remote-type ultrasonic level transmitter (e.g., Nikeson's LIQ-ULS-B) because of its convincing powers that it can quite simply not do without in the modern systems.

How Ultrasonic Level Measurement Works

The principle of ultrasonic measurement is simple but firm: a pulse of ultrasonic energy is fired onto the liquid surface and returned, and the round-trip time is measured. The "time-of-flight" is then used to determine the distance and liquid level. Contactless, it escapes sensor wear and contamination—giving increased life and more consistent accuracy even in harsh conditions.

Advantages of Ultrasonic Technique


1. High Accuracy and Resolution

There is precise measurement of levels at all times by ultrasonic transmitters. For example, the Nikeson LIQ-ULS-B measures to ±0.5% full scale (FS), and it is simple to control liquid inventory tightly.


2. No Contact, No Problems

No contact with the liquid means ultrasonic devices are not subject to corrosion, fouling, and mechanical wear. The non-contact mode encourages greater longevity and less maintenance.


3. Smart Diagnostics and Fast Response

The remote-type transmitter's 2-second fast response is only applicable to immediate monitoring functions. It also includes self-diagnosis technology that detects faults directly in order to support proactive maintenance.


4. Environmental Condition Flexibility

Incorporated are different working-condition algorithms and automatic temperature compensation that provide measurement accuracy within changing temperatures and extreme environments.


5. Multiple Output Options

Standard models are 2 or 4 relay outputs and optional isolated 4-20 mA analog output, so these transmitters will fit into an enormous majority of control systems.


Technical Specifications of the Remote-Type Transmitter (LIQ-ULS-B)

Following are a few points that highlight the new flexibility of this model:


Measuring Range: Optionable for 0–5 m, 0–10 m, or 0–15 m.


Blind Zone: Restricted blind zones—≤ 0.3 m (5 m range), ≤ 0.35 m (10 m), and ≤ 0.5 m (15 m).


Display: Monochrome LCD of high brightness to show current level.


Power Supply: Both 100–240 VAC (max 5 W) and 18–28 V DC are available.


Durability Rating: Converter IP65 rated, sensor IP68 rated, with max 30 m cable.


Why It Matters Across Applications

Water Storage & Fire Safety

In fire water tanks or well reservoirs, precise and continuous level measurement is essential. The dependability and quick response of ultrasonic transmitters give worry-free system readiness and compliance. 


Wastewater & Environmental Monitoring

Liquid-immune debris-resistant non-contact sensors and corrosive liquids are not subject to liquids and will not clog—highly suitable for these extreme environments—for sewage or reservoir monitoring.


Industrial & Chemical Processing

Process tanks hold hazardous chemicals or flammable atmospheres. Non-contact ultrasonic measurement offers safe, accurate, and maintenance-restricted performance—critical to keep production within tight control.

Float & Board Level Indicator: A Robust Mechanical Solution for Tank Level Monitoring

Image
Where the attention eye of liquid level monitoring in gigantic storage tanks—particularly where ruggedness, simplicity, and precision matter—is in play—the LiquiLevel FBS Float & Board Level Indicator by Nikeson is the best choice. The tough, mechanical gauge skillfully marries traditional float-and-pulley mechanics with an externally constructed precision readout, providing reliable performance in industrial and commercial applications. 1. How It Works: The Basics of Float-and-Board Mechanics In the LiquiLevel FBS is a stainless steel float connected by cord and pulleys to an external indicator on an aluminum gauge board. As liquid levels within the tank rise and fall, the float rises and falls. That motion is transmitted mechanically to the display pointer, which moves freely on the gauge board (through the use of nylon roller guides). A two-wire guiding system stabilizes float movement accurately. The float is at the top for empty tank and bottom for full tank. It's a reall...
