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 easy operation 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 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 according to customer requirements: high-temperature and high-pressure design, selection of anti-corrosion materials, and installation design for various pipelines ensure the product's suitability for various on-site needs.

Metal tube rotameters are widely used in the measurement and process control of liquid, gas, and steam media in industries such as petrochemicals, chemicals, metallurgy, electricity, food, pharmaceuticals, papermaking, and water treatment, due to their excellent performance, reliability, and cost-effectiveness.

I. Brief Introduction:

This series introducesHorizontal T-type metal tube float flowmeterThe 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 T-type structure is commonly used. Indicators can be selected from various other types to meet on-site requirements.

Overview:

    Metal tube float flow meterThe (Metal Tube Rotameter) is a commonly used variable area flow measurement instrument in industrial automation process control. It features a compact size, wide measurement range, and ease of use. It is suitable for measuring the flow of liquids, gases, and steam, particularly for low flow rates and low volumes. Over the years, the metal tube float rotameter has been widely applied in industries such as petrochemicals, steel, electricity, metallurgy, light industry, food, pharmaceuticals, and water treatment, thanks to its excellent performance, reliability, and favorable performance-to-price 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 5 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-side outlet type, side inlet-side outlet type, and side inlet-top outlet type. Each type also features standard models, high-temperature models, jacketed models, etc.

Horizontal Mount TypeFlowmeterFor diameters less than or equal to DN50, choose T-type structures; for diameters greater than DN50, opt for spring-loaded structures.

Flowmeter Connection SpecificationsThe TF series metal tube float flowmeter standard model adopts the GB/T9119-2000 flange standard, which can be customized according to customer requirements. Threaded and clamp connection methods are also available.

Indicator Selection:

Users can select from on-site display, battery-powered, wired remote, intrinsically safe, explosion-proof, or HART protocol-enabled models based on actual site requirements. Detailed functional descriptions of various indicators are listed in the table below.
