General:LSZ Serials Double-Rotator Flowmeter (Also called Bi-Rotor Flowmeter) is a self-research and designed product by Shanghai Yinuo Instrument Co., Ltd. This Series fflowmeter is a new kind positive displacement flowmeter developed specifically to serve as the heart in loading facilities at oil product depots. Contained in measuring chamber are a pair of rotators having special spiral gear teeth, the design of which is responsible for successfully eliminating pulsation in flow stream. The special sands proof and self-lubricant designing can measure sands content and high water contain oil. This type flowmeter has many advantages such as high-precision, high security, smooth running, low noise and long lifetime. Patent No:ZL-00216334.9 and ZL-99250679.4. Feature: 1) Superior Accuracy to 0.1%  2) Uniform rotation means low pressure loss 3) Long service lifetime  4) Self-lubrication  5) Very low noise and vibration 6) Easy maintenance 7) Low Pressure Drop 8) Double Cases

1.Pipe Connection        See Below Picture
a. The installing position should select without large vibration, extrem temperature and high magnetic field interfere. And the position is also easy installing and maintenance.
b. When installing flowmeter to a new pipe, the pipe should be cleared thoroughly before install flowmeter to pipe.
c. The flowmeter can be installed at any angle. There should leave enough space for maintenance.The picture is a sample of installation.
d. Please notice that the flow direction should same as the arrow on the flowmeter body.
e. A filter or strainer should install before the flowmeter avoid flowmeter blocked by impurity. When gas content in the measured liquid, A gas eliminator recommend to install before flowmeter. A gas eliminator can expell the gas in the liquid to better the accuracy.
f. The flow adjusting valve should install down stream of the flowmeter.
g. When the meterhead can not easily to be read, the user can remove the bolt of the flowmeter and circled the meterhead to the easily read direction.
h. For the material of cast steel steel flowmeter, there should avoid water flow in the flowmeter. The water may cause the rotator rust and block.

2. Wiring
When need signal output, please wire and install according to the manual of the LPJ Photoelectric Pulse/Current Generator.
