ツクバリカセイキ List of Products and Services

Water is supplied to the overflow tank by a pump, and static water at a constant pressure flows into the open channel.

• Other measuring instruments

Our company is capable of constructing a system that combines a 5-hole yaw meter, a traverse, and a computer to measure the distribution of flow direction and velocity by moving measurement points sequentially.

• Air compressors, blowers and pumps

The pressure value can switch between time-averaged display and display units (mmH2O/Pa). Additionally, it is equipped with an analog output terminal (0-5V) and an RS-232C port on the back, allowing it to connect to other information devices to capture data.

• Other measuring instruments

To measure the differential pressure of devices such as Pitot tubes and orifices at multiple points with a single differential pressure gauge, a switching cock is used.

• Other measuring instruments

In measurements such as flow velocity distribution, boundary layer measurement, and average airflow measurement using the JIS 5-point method, it is necessary to precisely move the Pitot tube and correlate the measurement values with their positions.

• Other measuring instruments

It is the most theoretically superior and reliable method for mechanically measuring the flow rate of gases and liquids. The flow rate within the pipe can also be determined from the cross-sectional area of the pipe and the average flow velocity. The tip of a standard Pitot tube has a total pressure port, and there is a static pressure port on the side. By inserting the Pitot tube into the flow pipe as shown in the diagram, the difference between total pressure and static pressure, that is, the dynamic pressure, is measured with a manometer, and the flow velocity is calculated using the following formula.

• Other measuring instruments

This device measures the flow pressure loss characteristics, which is an important performance evaluation item of the catalyst carrier incorporated in automotive exhaust gas purification systems. It consists of a wind tunnel, a blower, and a control computer.

• Air compressors, blowers and pumps

This device is an apparatus for testing the heat dissipation performance of automotive radiator cooling systems based on JIS-D-1614.

• Other measuring instruments

The most widely used type of wind tunnel for wind tunnel experiments is the circulating flow type, which has cross-sectional shapes of square, octagonal, and circular.

• Other measuring instruments

It is most suitable for intuitively understanding aerodynamic flow phenomena and can be easily used for educational and basic flow experiments.

• Other measuring instruments

It can be used as a standard instrument with wind speed distribution below 1% and turbulence below 1%. It is also possible to add a rotating device for calibration purposes, such as for a Yomeeter. The compact type has been miniaturized for installation in a laboratory, with turbulence at 0.5%.

• Anemometer

It is used to predict and solve various wind-related issues such as the wind tunnel effect around high-rise buildings, wind pressure acting on buildings, and the dispersion of urban pollutants.

• Building Cleaning Equipment
• Air compressors, blowers and pumps

In fields such as aviation, vehicles, automobiles, and fluid machinery, it is necessary to clarify and verify the mechanisms of noise generation using wind tunnel experiments and CFD (Computational Fluid Dynamics) in order to develop environmentally (Ecology) and economically (Economy) friendly ECO products through the reduction of aerodynamic noise and improvement of efficiency.

• Other measuring instruments

This device is designed to test the P-Q characteristics of fans with very small airflows. JIS-B-8330 "Fan Performance Testing Methods" is not suitable for testing fans with very small airflows, such as those used for cooling laptops. By using a mass flow controller in the airflow detection section, it has become possible to test fans with very small airflows.

• Air compressors, blowers and pumps

This device is a fan airflow measurement system based on AMCA and JIS standards, using a multi-nozzle method. It can be used for performance testing of various small fans. By combining it with the F-411 flow calculation system, automatic measurement of the fan's P-Q characteristics can be performed. In automatic measurement, parameters such as fan speed, voltage, and current can be measured simultaneously. There are two methods for switching the multi-nozzle: one is automatic switching via software, and the other is manual switching.
