1. Operating Principle:
Â
Liquid flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical signal is generated in the pickup coil. This signal is converted into engineering units (liters, cubic meters, gallons etc.) on the local display where is applicable. Optional accessory modules can be used to export the signal to other equipment.
Â
Upon receipt, examine your meter for visible damage. The turbine is a precision measuring instrument and should be handled carefully. Remove the protective plugs and caps for a thorough inspection. If any items are damaged or missing, contact U-IDEAL.
Â
Make sure the turbine flow model meets your specific needs. For your future reference, it might be useful to record this information on nameplate in the manual in case it becomes unreadable on the turbine. Refer to the nameplate for your customized product's specification.

A Derrick Crane is docking equipment installed on vessels or dockside. Derrick crane consists of derrick and hoisting mechanism. There are 3 or 4 steel wires connecting the derrick and hoisting mechanism, which controls hoisting mast goes up and down. A separate steel wire sling runs under the hoisting mast with a hook as the hoisting mechanism.
Features of Weihua Derrick Crane:
1. There are 4 driving system for the hoisting mechanism, 2 driving system for luffing mechanism.
2. The whole derrick crane chassis adopt basin support on concrete foundation, which can effectively ease the horizontal and vertical deformation of the derrick crane.
3. Multi-layer winding line reel drum. Hoisting winding drum wrapped with 4 layers of wire rope, and luffing drum is wrapped with 5 layers of wire rope.
4. Complete frequency control, half load lifting speed is 2 times faster than the full load lifting speed.
5. Inverter, encoder and electronic control system to ensure the 4 hoisting motors keep synchronous working.
