The world's first ultrasonic flowmeter
that was put into practical use in 1963.
In 1963, Tokyo Keiki developed the world's first flow meter using the ultrasonic method.
Mechanical flowmeters, which had been the mainstream until then, had problems such as high installation costs and large measurement errors.
However, the developed ultrasonic flowmeter has the features that the installation effort is much smaller and the measurement performance is higher than the mechanical type.
This feature was highly evaluated and quickly became popular in the field of flow measurement in Japan.
The latest weighing system using a rotary diverter, an overflow type elevated water tank with a height of 25 m, a pipeline test line equipped with 11 types from large diameter to small diameter compliant with ISO17025, and the first open channel test line in Japan. I own.
Tokyo Keiki, which has the world's first practical application of ultrasonic flowmeters and abundant achievements, uses this state-of-the-art actual flow rate calibration equipment to provide the optimum flowmeter calibration service for customers.
Since launching the world's first ultrasonic flowmeter in 1963, our products, which have accumulated the longest experience in the world, support water resources and production control sites.
The ultrasonic method enables non-contact, safe and secure measurement.
It boasts a market share of over 60% in the water and sewage, agricultural water, and hydroelectric power plant markets in Japan.
Field Application Example
Microwave Level Gauges
The non-contact radar level meter realizes better and higher stability for plant management of food and beverages, chemical tanks, etc., and river water level monitoring.
The radar level meter has high resistance against environmental changes and achieves high accuracy and high stability.
In addition, non-contact measurement realizes safely and securely and the least maintenance required.
