LLQ SERIES GAS ROOTS FLOWMETER

 

 
       
 

2 Functions and Features:
鈻 The rotor and shell of flowmeter uses CNC machining center to process precisely and balance. The rotor adopts packing grains which are high-temperature and ultrafine for surface treatment. When it works, it doesn鈥檛 have any abrasion. There is no contact-type seal. It has the function of self-cleaning and can lubricate the bearing very well. The marstely design and machining technics can ensure that flowmeter can work normally for a long time.
鈻 The high precision doesn鈥檛 need to regulate forever. It will never be affected by the change of medium鈥檚 working condition. The starting flow is small. The pressure loss is little. The span ratio is wide. It is used to measure the micro flow.
鈻 The product has wonderful intellectualization and powerful functions. It has the functions of signal outputing and traffic data storaging.
鈻 The product has a lot of structural type, such as mechnical accounting type, versatile numeric type, and the compound type of mechnical and versatile, which is convenient for the users.
鈻 It combines the flow temperature, pressure sensor and intelligent flow totalizer into one, which can output and control the flow signal.
鈻 The gauge outfit of flowmeter can rotate any directions by 180掳 and is easy to installate.
