FC-100 UPW Flow Controller for Chemical Industry Systems

Application in chemical-industry DI and ultrapure-water systems

FC-100 is a pressure-balancing flow controller from Particle Measuring Systems for liquid particle counters used in deionized and ultrapure-water sampling systems. It can support chemical manufacturing, chemical-quality laboratories, component-cleanliness testing, and process or filter monitoring where stable high-purity water flow is required. The controller is not a particle counter and does not detect, size, or count particles by itself. It controls water flow through a compatible PMS liquid particle counter.

Changes in system pressure can alter sample flow and reduce the comparability of particle data between time periods or monitoring points. Tự động điều chỉnh theo biến động áp suất mà không cần can thiệp vận hành. A properly selected flowmeter range must match the required flow rate of the connected particle counter. The complete system design should also consider tubing, fittings, sample-point pressure, temperature, drain conditions, and the particle counter's operating limits.

How FC-100 differs from the other controller

FC-100 uses a single operating flowmeter and automatically responds to pressure changes. Available flowmeter ranges are selected to match the required particle-counter flow. It is suited to stable UPW monitoring points that require automatic pressure balancing but do not require an integrated high-flow flush path. Both FC-100 and FC-200 are intended to automatically compensate for system-pressure changes and support stable sample flow, but they are not interchangeable merely because their external dimensions and general material specifications are similar.

FC-100 is the simpler configuration for normal pressure-balanced flow control. FC-200 adds the dedicated high-flow flush path. The flush function is useful when air or residual particles must be removed from the line and counter before reliable data collection resumes. Flushing does not replace correct installation, cleanliness procedures, leak checks, or the stabilization criteria defined by the facility.

Published operating limits and materials

The published fluid-pressure range is 20–100 psi, and the fluid-temperature range is 0–90 °C. The assembly weighs 2.3 kg and measures 29 × 18 × 13 cm. The flow controller uses a Moore model 63SD mechanism. Listed materials include 316 stainless steel for the body, differential spring, valve-plunger seat, and plunger spring; Kynar® PVDF for the diaphragm; and PFA, nylon, or 316 stainless steel fittings depending on configuration.

Flowmeter wetted internal parts are 316 stainless steel, seals are Viton®, and the metering tube is borosilicate glass. The published flowmeter accuracy is 10% of full-scale flow rate with water at 21.1 °C. This is a full-scale specification, not 10% of the instantaneous reading. Material compatibility and actual system performance must be assessed for the exact water quality, temperature, pressure, cleaning method, fittings, tubing, and selected flowmeter range.

Typical UPW uses and selection information

Typical applications include deionized-water sampling systems in chemical plants, high-purity process-water monitoring, laboratory water sampling, parts-cleanliness testing, and process or filter monitoring. The controllers are also technically applicable to semiconductor-grade UPW systems, but SAO NAM does not distribute them to electronics-industry customers. Before selection, provide the connected particle-counter model, required flow rate, normal and maximum pressure, water temperature, tubing and fitting requirements, sample-point layout, drain arrangement, and whether a high-flow flush is required.

For an installed controller, the model label, part number, serial number, flowmeter range, photographs of the tubing connections, and observed flow behavior help identify the correct service or replacement scope. Current PMS documentation should be checked before changing the flowmeter, controller, tubing, or connected particle counter.
