Metal tube rotor flowmeters (metal tube float flowmeters) are commonly used process monitoring, control, and measurement instruments in industrial automation processes. They feature 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 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 for user-specific requirements is available: high-temperature and high-pressure design, selection of corrosion-resistant materials, and various pipeline installation designs ensure the product meets diverse on-site needs.
Metal tube rotameters are widely used in the measurement and process control of liquid, gas, and steam mediums in industries such as petroleum, chemical, metallurgy, electricity, food, pharmaceuticals, papermaking, and water treatment, thanks to their excellent performance, reliability, and favorable cost-performance ratio.
I. Brief Introduction:
This series introducesLevel T-Type Metal Tube Float Flow MeterThe fluid inlet and outlet directions are left-in-right-out. The standard sensor material is 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. The indicator can be selected to be of other types as per on-site requirements.
Overview:
Metal tube float flow meterThe metal tube rotor flowmeter is a commonly used variable area flow measurement instrument in industrial automation process control. It boasts small 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 small volumes. Over the years, the metal tube float flowmeter has been widely applied in industries such as petrochemicals, steel, power, metallurgy, light industry, food, pharmaceuticals, and water treatment, due to its excellent performance, reliability, and favorable performance-to-price ratio.
Flow Meter 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 categorized into 5 types based on the direction of the fluid inlet and outlet: vertical type, horizontal type (further divided into 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 includes standard models, high-temperature models, jacketed models, and so on.
Horizontal Mount TypeFlowmeterFor sizes less than or equal to DN50, choose T-type structures; for sizes greater than DN50, opt for spring-loaded structures.
Flow Meter 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 choose from on-site display, battery-powered, wired remote, intrinsically safe, explosion-proof, or HART protocol-compliant models based on actual site requirements. Detailed functional descriptions of various indicators are listed below.
Indicator Type
Instrument Function Description
M1 Model
Local pointer indicates flow rate; no power required; no 4-20mA remote transmission; optional flow alarm device; scale can be set to instantaneous flow value or percentage scale value.
M3 Type
