Rockwin Flowmeter India Pvt. Ltd Sahibabad, Ghaziabad, Uttar Pradesh

Strainer along with the Air Eliminator can be used to disperse the air from the pipeline. Air in the pipeline can cause damage to the flowmeter and is also a source of incorrect flowmeter reading.

Rockwin’s Strainers are fabricated from certified materials by coded welders and hydrostatically pressure tested 1.5 times the working pressure. They have versatile design and constructions. The Inlet, Outlet and body sizes can be adapted to suit line size and pressure drop requirements. The product range of Rockwin included Basket Type Strainer. The available sizes are from ¾ inch to 20 inch in any mesh size.

Remote Area Totalizer is designed for inexpensive Totalization and Flow Rate Readouts of liquids and gases. Rockwin’s TMTR 8600 is meter mounted batter powered electronic unit. Remote Area Totalizer is housed in certified casing for Hazardous Area Applications. Pulse or Analog transmission facility is available as options.

The Pre Amplifier amplifies the low voltage signal from the Turbine Flowmeters into current pulses at a suitable level for transmission over long distances or through noisy environments. To minimize installation costs, these current pulses are modulated into the power supply lines so that the number of wires required for connection is reduced to two and number of safety barriers to one. It is designed to meet the requirement of Petroleum Industry, and is certified for Hazardous Area Applications. Rockwin's Pre Amplifier is enclosed in rugged conduit box, which is weatherproof to IP 65

The standard Pick-off Sensor are magnetic reluctance type. Each output is approximately 30 mV peak to peak at minimum flow. The frequency generated is directly proportional to the rotation of the Turbine Meter Rotor, or in other words, the flow rate. Different models of Pick-off Sensors are available according to the different areas of use such as standard, intrinsically safe, high temperature applications. Certification : II 1G/EEx ia IIC T6

Series 9000/7000 family of electronics is designed for indication and integration of flow, preset batching, hi-low alarms and analog outputs. Various models in standard DIN size enclosures are available for individual or any combination of the above features.

We are offering liquid turbine flowmeter. Rockwin turbine flowmeters are designed to provide a high order of accuracy & reliability under the severest conditions encountered in oil, gas, petrochemical, aerospace and other industries. These flowmeters are precise, reliable, rugged and built to international standards. Sizes range from 5 to 500 mm with flanged end connections and 5 to 50 mm with threaded end connections. All flowmeters are individually calibrated on rockwin's in-house certified calibration laboratory.

Rockwin’s series 5000 insertion turbine flowmeter is designed for applications where installation and removal from the pipeline without interruption to flow and economy of cost is important than extreme accuracy of measurement. These are ideally suited for use in large diameter pipelines where the cost of inline meters would be prohibitive. The installation and removal of these meters can be done through a suitable valve while the flow-line remains under pressure. Rockwin's insertion meters have wide rangeablity & improved linearity.

Flow Range : upto 12 M³/Sec (Liquid) upto 50 M³/Sec (Gas)

Repeatability : +/- 0.2% (95% confidence level)

Inline Turbine Flowmeter (TFM Series) Rockwin Turbine Flowmeters are designed to provide a high order of accuracy & reliability under the severest conditions encountered in Oil, Gas, Petrochemical, Aerospace and other industries. These flowmeters are precise, reliable, rugged and built to international standards. Sizes range from 5 to 500 mm with flanged end connections and 5 to 50 mm with threaded end connections. All flowmeters are individually calibrated on Rockwin's In-house Certified Calibration Laboratory.

Rockwin’s hygenic turbine flowmeters are designed for applications in the dairy, pharmaceutical, food and beverage industries. They are suitable for cleaning in place (cip) and can be installed in any attitude special meter lengths are supplied where it is essential to limit number of connections. The flowmeter can be connected to remote panel mounted readouts as well as integral mounted readouts. Weatherproof to I p 65.sanitary tri clover end fittings are available.

Flow Range : upto 135 M³/Hr

Accuracy : Linearity: +/- 0.5% over 10% to100% flow range Repeatability: +/- 0.05%

The use of Flow Straightners significantly improves the accuracy of measurement where application conditions are characterized by asymmetric and swirling flow. These Straightners make the flow laminar. The body of and the flanges are constructed from Carbon Steel and the straightening section (tube bundle) is manufactured from Stainless Steel 304 or 316. End Connections are available to ANSI DIN, BS or other standard specifications.

The F-I Converter converts millivolt pulses from a Turbine Flowmeter pickup into a 4-20 mA linear signal representing rate of flow. The output current is modulated on to the supply lines, so only two wires are needed to connect into the readouts. Rockwin's F-I Converter are certified for use in Hazardous Area Application. The rugged box is certified weatherproof to IP 65.

The custody transfer series inline turbine flowmeters are designed to provide high accuracy liquid flow measurement under the exacting conditions encountered in the oilpetroleum industry.
