Metal tube rotameter (metal tube float flowmeter) is a commonly used instrument for process monitoring, control, and measurement in industrial automation. It features a compact size, wide measurement range, and ease of use and maintenance.

Product Execution Standards: JB/T6844, JJG257.

The TF series features a full-metal structure transmitter with non-magnetic hysteresis and no mechanical transmission mechanism: the entire unit is based on modular design, including newly designed indicators, 4-20mA remote signal output modules, switch signal output modules, instantaneous and cumulative flow display, HART protocol, and MODBUS(RTU) bus. Customization is available to meet user requirements: high-temperature and high-pressure design, selection of anti-corrosion materials, and installation design for various pipeline types ensure the product's suitability for diverse field needs.

Metal tube rotameters are widely used in the measurement and process control of liquid, gas, and steam mediums in industries such as petrochemicals, metallurgy, electricity, food, pharmaceuticals, papermaking, and water treatment, thanks to their excellent performance, reliability, and favorable price-performance ratio.

I. Brief Introduction:

This series introducesLevel T-Type Metal Tube Float Flow MeterThe fluid inlet and outlet directions are left in and right out. The sensor material is standard 304 stainless steel (optional 316 or 316L). The indicator in the photo is a local pointer type. For horizontal flowmeters with an orifice size ≤ DN50, a common T-type structure is used. The indicator can be selected from other types according to site requirements.

Overview:

    Metal tube float flowmeter(Tube转子流量计) is a commonly used variable area flow measurement instrument in industrial automation process control. It features a small size, a wide measurement range, and ease of use, and is suitable for measuring the flow rates of liquids, gases, and steam, especially for low flow rates and small quantities. Over the years, the metal tube float flow meter has gained widespread application in industries such as petrochemicals, steel, electricity, metallurgy, light industry, food, pharmaceuticals, and water treatment, thanks to its excellent performance, reliability, and good performance-to-cost ratio.

Flowmeter Type:

The TF series metal tube float flowmeter consists of a measuring tube (sensor) and an indicator (electronic converter). By selecting different types of measuring tubes and indicators, various complete units can be assembled to meet on-site requirements.

The TF series metal tube float flowmeters are divided into five types based on the direction of the fluid inlet and outlet: vertical type, horizontal type (including horizontal T-type and horizontal spring type), bottom inlet and side outlet type, side inlet and side outlet type, and side inlet and top outlet type. Each type features standard, high-temperature, and jacketed versions, among others.

Horizontal installation typeFlowmeterWhen the diameter is less than or equal to DN50, use T-type structures; for diameters greater than DN50, use spring-type structures.

Flow Meter Connection SpecificationsThe TF series metal tube float flowmeter standard model adopts the GB/T9119-2000 flange standard, and the flange standard can be customized according to customer requirements; both threaded and clamp connection methods are available.

Indicator Selection:

Users can select from on-site display, battery-powered, wireless remote, intrinsically safe, explosion-proof, or HART protocol-compatible models according to their specific on-site needs. Detailed functional descriptions of various indicators are listed below.
