Company profile
Tokyo Keiso Co., Ltd. was founded in 1954 and specializes in the manufacture and supply of flowmeters and level gauges for flow and level measurement. Since its establishment, the company states that satisfying customer needs has been a basic principle across research and development, production, and sales. Its operating approach is built on three stated policies: direct sales and direct technical support by its own sales staff, a broad product range for different fields and measurement ranges, and active responses to new customer requirements. Sales staff work directly with customers to understand flow and level measurement objectives and recommend suitable products based on sales experience and technical judgement. The Taiwan-facing company information similarly presents a full series of flow and level measurement products together with direct sales and technical support, reinforcing the company's measurement-specialist positioning. Tokyo Keiso Co., Ltd. therefore combines instrument manufacturing with application selection and technical support rather than treating flow and level products as stand-alone catalog items.
Exhibits
Tokyo Keiso Co., Ltd. offers a wide lineup of flowmeters and flow controllers suitable for integration into semiconductor manufacturing equipment, chemical-solution systems, ultrapure-water systems, and other installations. Among these products are ultrasonic flowmeters made of fluororesin for measuring small liquid flow rates of ultrapure water and various chemicals. The fluororesin ultrasonic design has no moving parts and measures without contact between the sensor and the liquid, supporting small-flow measurement of ultrapure water and chemical liquids. The CLFC300 series is a flow controller that integrates the functions of an ultrasonic flowmeter, a control valve, and circuitry for flow computation and valve control in one product. Its control function is designed to follow the target flow rate quickly, linking ultrasonic measurement with active valve control rather than measurement alone. Tokyo Keiso identifies the CLFC300 series as suitable for liquid control in semiconductor manufacturing where chemicals require constant supply and where DIW and slurry flow must be controlled. The semiconductor-related offering therefore includes both measurement instruments and flow-control products, with specific coverage for chemical-solution systems, ultrapure-water systems, chemical supply, DIW, and slurry. For applications that require small-liquid-flow measurement without moving components, the fluororesin ultrasonic flowmeter provides the measurement approach, while CLFC300 adds valve actuation and control computation for target-flow regulation. These products fit the company's broader flow and level measurement portfolio and can be selected with direct technical support according to the customer's measurement target and system conditions. The combination of fluororesin ultrasonic flow measurement, no sensor-to-liquid contact, integrated valve control, rapid target-flow response, and semiconductor-specific chemical, DIW, and slurry use cases defines the detailed process-control capability described for this product group.
