Product Description
Oval meters are instruments used for the continuous and intermittent measurement and control of the pipe liquid flow, which are typical of positive displacement meter, feature large flow range, low pressure loss, large viscosity range, easy installation, high accuracy and can neasure high temperature, high viscosity liquids with easy calibration. The meters are widely used for the flow measurement in th field of petroleum, chemical, chemical fibre, traffic, food industries and commerce, medical and sanitary departments.
For the different liquids (acid, alkali, salt, organic solution etc. ), the metrrs can be made of different materials (casted iron, casted steel, stainless steel etc, aluminium. ) with the material code as follows: A represents casted iron, E represents casted steel, B represents stainless steel (1 Cr18Ni9Ti), and L represents aluminium.
Oval meter is generally comprised of a flow transducer and a counter mechanism. The main part of the transducer is a measuring chamber which consists of a pair of oval wheels and a sealing coupling. The counter mechanism contains speed reduction gears, adjusting device, counter, and pulse transtmitter (Type LC12) etc.
In the measuring chamber, a pair of oval wheels and cover plate make a cresant shape cavity which is used as a measuring element. The oval wheels are rotated by the pressure difference in the inlet and out-let of the meter and drive the inlet liquid through the cavity to the outlet, each revolution of the oval wheels displaces fluid four time the volume of the cavity, the total revolutions of the oval wheels and the revolution rate will be transferred to the mechanical counter, and the total liquid volume and instantaneous flow will be known by the pointer display and the roller intergration. The attached signal gene-rator converts the rotary axial angular shift to the pulse signal and then transmitters it to the electrical indicator for remote intergrated flow and instantaneous flow indication and control.
Hefei Jingda Instrument Co., Ltd. is a large-scale key enterprise in the fields of device and instrument, specialized in manufacturing various flow meters with the largest turnover of oval flow meters in China.
Our factory was founded in the year of 1958, covering an area of 70, 000sqm. We have a technology center, and a flow test and calibration station, and own advanced equipment, well-developed technologies, and test and calibration equipment.
During the recent ten years, we have adopted up-to-date technologies transferred from BOPP & Reuther AG, Germany, Oval Corporation, Japan to produce oval flow meters and vortex flow meters, which reach the international level of the nineties. OI Oval flow meter for marine application has been listed as the product which can take place of imported products by the national authorities. Type OI 50 was awarded the first gold medal in the national instrument and process control industries. Besides, our factory has developed and produced helical flow meters, steam flow meters, Root flow meters, wedge flow meters, strainers, high viscosity pumps and micro-processor based flow computers, indicators and totalizers for flow meters. Our products sell well in petrochemical, metallurgical, power, foodstuff and martial fields, and scientific research departments at home and abroad.
In the year of 1996, a joint venture of Hefei Oval Instrument Co., Ltd. Was set up by Hefei Jingda Instrument Co., Ltd and Oval Corporation, Japan to produce UF Flow meters.
Looking into the future, Hefei Jingda Instrument Co., Ltd. Will endeavor to provide customers with quality products and first-rate services.
