Precise and Long-Lasting Measurement with Ultrasonic Agricultural Irrigation Meter
Accurate measurement of water consumption in agricultural irrigation is critical for both cost control and efficient use of water resources. Ultrasonic agricultural irrigation meters set a new standard in the agricultural sector by eliminating all disadvantages of mechanical meters with modern technology.
What is an Ultrasonic Irrigation Meter?
Ultrasonic irrigation meters are new-generation measurement devices that use sound waves to measure water flow. Instead of propellers, impellers, or moving parts found in traditional mechanical meters, measurement is performed by sending encrypted ultrasonic waves through sensors placed opposite each other.
Working Principle: The velocity of the water passing through the meter is calculated from the changes in the transmission time of the ultrasonic sound waves. This method provides high-precision measurement without mechanical friction.
Ultrasonic water meters produced locally in Turkey are manufactured with MID (Measuring Instruments Directive) certification and TSE certification. The Esular brand offers these technologies to farmers by integrating them with modern smart irrigation systems.
Advantages Over Mechanical Meters
There are many problems with using mechanical meters in agricultural irrigation. Ultrasonic meters solve these problems fundamentally.
No Moving Parts, No Wear
Plastic propellers and impellers in mechanical meters are worn down like sandpaper by even the smallest particles in the water. Over time, this wear causes incorrect measurements or complete failure.
Ultrasonic meters are shaped like a straight pipe and contain no moving mechanisms. Thanks to this, they are not affected by sediment, moss, or debris. No wear problems occur over time. They have a lifespan twice as long as mechanical meters.
Does Not Measure Air
One of the biggest problems with mechanical meters is that they count air passage as water. This situation causes significant financial losses, especially in agricultural irrigation. Ultrasonic meters only measure water flow; the meter does not operate during air passage. Thanks to this feature, you know exactly your real water consumption.
High Precision
Ultrasonic meters have a dynamic measurement range between R315 and R400. Mechanical irrigation meters generally have a dynamic range of R25, maximum R160. An R400 value means there is a 400-fold difference between the lowest flow rate and the highest flow rate. It performs precise measurements even at very low flow rates. It provides Class 2 accuracy across a wide flow range.
10-Year Battery Life
Ultrasonic meters offer a battery life of up to 10 years thanks to low energy consumption. The lifespan of mechanical meters in agricultural irrigation is at most 2 years.
No Pressure Loss
The propeller system in mechanical meters creates resistance to water flow, causing pressure loss. This increases pump costs. Ultrasonic meters create very low pressure loss. They reduce energy consumption caused by the pump. Thanks to the straight pipe structure, there is no risk of clogging.

Esular Smart Irrigation Ecosystem
Ultrasonic agricultural irrigation meters work in perfect harmony with the esular smart irrigation ecosystem.
Remote Monitoring
Data received from your meter is transferred to the central system via LoRa RF or GSM-GPRS. You can view your instant water consumption via the Esular mobile application or web panel. You can access historical consumption reports. You receive warnings in case of abnormal consumption. You can perform water leak detection.
Automatic Irrigation Control
When you use the ultrasonic meter together with the esular Wireless Smart Valve Control Unit, automatic valve control is provided according to the amount of water you determine. You can set a separate water quota for each irrigation zone. When the target water amount is completed, the valve closes automatically. Water savings and cost control become fully possible.
Pump Control System
When you use the Esular Wireless Well and Pump Control System together with the ultrasonic meter, pump operating times and water consumption are compared. Pump efficiency is monitored. In case of abnormal consumption, the pump can be stopped automatically. Energy and water savings are provided together.
Model Selection
Ultrasonic agricultural irrigation meters are produced in different DN (nominal diameter) values. To choose the correct model, you need to know the flow rate of your irrigation system.
Flow Table for Medium and Large Agricultural Lands:
| Model | Minimum Flow Rate | Transitional Flow Rate | Continuous Flow Rate | Overload Flow Rate |
|---|---|---|---|---|
| UTM80 | 0.25 m³/h | 0.4 m³/h | 63 m³/h | 78.75 m³/h |
| UTM100 | 0.25 m³/h | 0.4 m³/h | 100 m³/h | 125 m³/h |
Different diameter options are available at the Esular store.
Installation and Usage
It can be used in any direction. It is not affected by inclined installation. Installation is simple thanks to the straight pipe structure. It does not require installation precision like mechanical meters.
Since there are no moving parts, periodic maintenance is not required. No intervention is needed other than battery replacement. Transducers can be replaced under pressure.
The meter gives an alarm and shuts down when the cover is opened. When the union is opened, the tamper switch is activated. Secure access is provided via RFID card. User and technician cards can be defined separately.
Prepaid System
Ultrasonic meters can also be used with a prepaid system. Payment is made before water use. Collection problems are eliminated. Users pay as much as they consume. When credits run out, the valve integrated into the meter closes automatically. Credits are easily loaded with a card reader. Excess water use is prevented.
Why Ultrasonic Meter?
Agricultural irrigation takes the largest share of water consumption in Turkey. Efficient use of water resources and accurate measurement are critical for both individual farmers and the national economy.
With ultrasonic agricultural irrigation meters, you measure your real water consumption precisely. You do not pay for air or incorrect measurements unfairly. You can use it safely for 10 years. You save on maintenance and replacement costs. It works integrated with modern irrigation technologies. You gain remote monitoring and control opportunities.
Together with the Esular ecosystem, you can establish a fully automatic irrigation system. Water and energy savings are provided together. You control it from anywhere with the mobile application. You can perform AI-supported smart irrigation planning.
Conclusion
The use of ultrasonic meters in agricultural irrigation is no longer a luxury but a necessity. Considering the short lifespan of mechanical meters, clogging problems, air measurement issues, and low precision, ultrasonic meters provide a clear advantage.
Ultrasonic meters should definitely be preferred, especially in systems where non-clean irrigation water is used, in large-diameter pipe systems, in facilities where remote monitoring and control are required, in agricultural lands requiring precise water management, and in projects where prepaid systems will be used.
