1 ULTRA OVAL Meter Sizes:9, 4, 45, 50, 5, 5 w/unfactored Pulse Generator (NPG60A) GENERAL SPECIFICATION GS.No.GBU0--E GENERAL ULTRA OVAL MODEL 9, 4, and45 provides extensive capability as a highly dependable OVAL flowmeter to be used for various application in process where accurate flow measurement of low flow rate is required. FEATURES. Accurate (Linearity) to ±0.5% or better. Well suited for small flow measurements.. Pocketless design of measuring chamber construction makes the flowmeter ideal for fine chemicals, foods, pharmaceuticals, cosmetics and etc., furthermore, simplifies maintenance and inspection work.. Flowrate information is transmitted by the pulse generator in the form of a noncontact pulse signal compatible with highly sensitive and reliable remote instrumentation. 4. Absence of any mechanical transmission requires no loss in torque and ensures long service life. 5. Flow totalizing and instantaneous flowrate indication are monitored in a LCD counter independently mounted.

6 STRAINER It is necessary to install a strainer directly before the flow meter or as close as possible on the flow input side, so that solid particles mixed in the fluid do not enter the flow meter and causes problems.

7 POINTS OF CAUTION These flowmeters used to measure minute flow rate are precisely adjusted in the factory, so it is necessary to take special care when unpacking, installing in the piping and testing. Never let foreign materials enter into the measuring chamber. Flush the piping well enough before installation. It is essential that you always avoid violently spinning the rotor by flushing air or an excessive flow rate in a short period of time. Only use Oval's strainer dedicatedly designed for these flowmeters. PLEASE SUPPLY THE FOLLOWING INFORMATION WHEN YOU INQUIRE.. Model L. Fluid to be measured Name Viscosity mpa s Specific gravity.
