Compartment loads - tanker

Are you using a pump?

 

Does your pump change tone when it runs dry or cavitates?

 

Sometimes when the plant is noisy and I can't use gauges I have to put a screwdriver on a hose clamp and rest my ear on it. Like a redneck stethoscope. I can hear flow real good though. Operator at the Valero refinery in Three Rivers TX showed me that little trick.

 

How are you going to vent it?
Do you have vapor recovery if so that'll work.
Listen for a chanve in the sound of the pump.
My pump will bounce my hoses a little bit when mt.

 

well you need to go up and vent the tank if that's not a option usually the pump gets a little louder when you empty a compartment

 

Unless your tank has a vapor recovery line, no need to go on top.
Once you start off loading feel how heavy the hose is. When it's empty it's lighter.

 

Hold your hand over the VR opening. When the compartment goes empty, you'll feel a reduction in the amount of air being pulled into the trailer.
