Description

Kofloc Model RK1250 Flow Meters and Controllers for Liquid

Kofloc Model RK1250 An area flow meter has a float in a conical cylinder (tapered tube) with a larger end in the upper section and a smaller end in the lower section. The float moves up and down according to the intensity of the flow, and the position at which the float balances indicates the flow rate. Not only simple flow meters that merely measure the flow rate but also flow meters with a valve for flow control, flow meters with a load pressure fluctuation type flow controller, flow meters with a supply pressure fluctuation type flow controller, and flow meters with an alarm switch are available.

The Model RK1250 Series Flowmeter is a completely renewed model of the existing KOFLOC RK1200, designed as a flowmeter that can be integrated into the customer’s equipment. A combination of a grade high precision float type flowmeter with a needle valve capable of very accurate flow control provides a flowmeter ideal for measurement and control of trace flows.

Features

High-Precision Liquid Control: Integrated micro-adjustable needle valve provides smooth, high-resolution control for low-to-medium liquid flow rates.
High Flow Capacity Design: The RK1250 series accommodates larger flow tube capacities than compact purge meters, making it ideal for primary liquid lines.
Clear Parallax-Free Scale: High-contrast scale etched directly on the pyrex glass tube ensures fast, accurate visual readings.
Robust Body Construction: Available in Brass and 316 Stainless Steel bodies to handle pure water, mild acids, solvents, and industrial reagents.

Applications

Chemical Dosing & Injection: Precise manual regulation of liquid catalysts, additives, and neutralizers in chemical reactors.
Water Treatment & Purification: Liquid flow monitoring in reverse osmosis ( $RO$ ) permeate lines, deionizers, and dosing pumps.
Industrial Cooling Systems: Controlling coolant and demineralized water flow to high-frequency induction furnaces and machinery heat exchangers.
Pilot Plants & R&D Laboratories: Accurate liquid metering for continuous liquid-phase chemical synthesis and university test rigs.
