Metal tube rotor flowmeters (metal tube float flowmeters) are commonly used instruments for process monitoring, control, and measurement in industrial automation. 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. Custom configurations can be produced according to customer requirements: high-temperature and high-pressure design, selection of anti-corrosion materials, and installation designs for various pipe 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 oil, chemical, metallurgy, power, 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 meterFluid inlet and outlet direction is left in, right out. The common 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. Indicators can be chosen from other types according to site requirements.
Overview:
Metal Tube Float Flow MeterThe (Metal Tube Rotameter) is a commonly used variable area flow meter in industrial automation process control. It boasts features such as a compact size, wide measurement range, and ease of use. It is suitable for measuring the flow rates of liquids, gases, and steam, particularly for low flow rates and small volumes. Over the years, the Metal Tube Float Flowmeter has gained widespread application in industries such as petrochemicals, steel, electricity, metallurgy, light industry, food, pharmaceuticals, and water treatment, due to its excellent performance, reliability, and favorable performance-to-cost ratio.
Flowmeter Type:
The TF series metal tube float flow meter 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 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, etc.
Horizontal Installation TypeFlow MeterFor 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, and the flange standard can be customized according to customer requirements; both threaded and clamp connection methods are also available.
Indicator Selection:
Users can choose from on-site display, battery-powered, wireless remote, intrinsically safe, explosion-proof, or HART-protocol-compatible models according to their actual needs on-site. 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 selected for instantaneous flow rate or percentage scale value.
