Simple water level gauge for measuring water levels in fields.

Simple water level gauge for measuring water levels in fields.

The water level gauge improvement consortium project for rice paddies has been adopted by the Ministry of Agriculture, Forestry and Fisheries as part of the "Fiscal Year 2021 Smart Agriculture Technology Development Support Project"!

Our company is located in Okayama Prefecture, which is known for its thriving fruit cultivation, such as peaches and grapes, while also producing high-quality rice. Thanks to the warm climate, abundant sunshine referred to as the "Land of Sunshine," and the rich water from three major rivers, we cultivate high-quality rice. Asahi rice, which is beloved in the prefecture, has been valued for sushi rice since ancient times and is considered the root of Koshihikari rice. This time, we aim to realize a remote monitoring system utilizing IoT technology in collaboration with the Bichu Prefectural Agricultural, Forestry and Fisheries Department (Niimi Agricultural Extension Center). As part of our activities, we will develop a low-cost water level meter focused on measuring water levels in fields, investigate its usability, accuracy, and durability, and promote the dissemination of simple water level meters based on the results. 【Features】 1. Easy installation. Simply insert the sensor at any location within the field. 2. Built-in charging function, eliminating the need for electrical work. 3. Data can be checked from anywhere. 4. Uses high-precision and low-cost sensors. 5. Usable even in distant fields. *Please feel free to contact us for more details.

[Industry First] Easy installation without construction. It is a non-contact water level gauge.

1. Easy installation without the need for construction 2. High specifications at a low price 3. Simplified inventory management through telemetering 【Easy Installation】 It can be easily installed with silicone rubber sealant on existing tanks without any construction. Therefore, there is no need to replace the tank, nor is there a need to penetrate the tank to install the sensor. 【High Specifications】 Despite being an external tank, its accuracy is comparable to that of other products. The measurement accuracy is ±2 millimeters (depending on the measured object), and the measurement distance is up to 3 meters. It can operate in temperatures ranging from -20°C to +125°C. Additionally, explosion-proof sensors are also available. 【Telemetry】 By monitoring the tank's water level via mobile phone signals, it reduces labor costs and ensures that no sales opportunities are missed. 【Usage Example】 Before delivering propane gas to clients (such as restaurants), this product is installed on the tank prior to delivery. The usage can be checked from the sales office through telemetering, allowing for a reduction in unnecessary labor costs and enabling timely sales efforts. Furthermore, since this product does not require specialized installation, the introduction costs can be kept low.

Optical Crystal Water Level Gauge "OPQS Series"

Optical Crystal Water Level Gauge "OPQS Series"

Using optical fiber for data transmission between the sensor and the converter! Achieving high-precision water level measurement.

We would like to introduce our optical quartz-type water level gauge, the "OPQS Series." The optical quartz-type water level gauge converts the frequency signal from the quartz oscillator into an optical signal (SM) at the E/O conversion section within the sensor and transmits it. This product has a built-in battery inside the sensor as its power supply. The quartz oscillator used in the water level measurement section changes its resonant frequency linearly in response to the applied water pressure, and since the rate of change is large, it enables highly accurate water level measurement. 【Features】 ■ High Precision: Utilizes the principle of the highly regarded quartz-type water level gauge for accurate water level measurement. ■ Lightning Protection: Uses optical fiber for data transmission between the sensor and the converter. *For more details, please refer to the PDF document or feel free to contact us.

Water temperature compensated crystal-type water level gauge "QSR Series"

Water temperature compensated crystal-type water level gauge "QSR Series"

Achieves high-precision and stable water level measurement. The construction method is easy, just like the water level gauge, and maintenance management is also simple.

The "QSR Series" is a pressure-type water level gauge that utilizes a quartz crystal oscillator. The quartz crystal oscillator changes its resonance frequency linearly in response to the applied water pressure, and due to its large rate of change, it enables high-precision and stable water level measurement. The quartz water level gauge with temperature compensation measures water temperature using one temperature sensor inside the level gauge sensor and five sensors within the sensor cable, totaling six temperature sensors. By performing density correction with a dedicated water level gauge recorder, it is possible to maintain high precision measurements even in cases where the water depth is deep, such as in dams, and there are temperature differences in the water. 【Features】 ■ High precision and stability ■ Elimination of density difference effects ■ Water temperature measurement and density correction with six temperature sensors ■ Easy installation and maintenance ■ Temperature sensors built into the water level gauge sensor cable *For more details, please refer to the PDF document or feel free to contact us.
