Lubrication flow meter

Abstract

The lubrication flowmeter is configured to be a part of the lubrication system to grease frack valves. The system generally utilizes a manifold to connect to the various fracked valves and at least one pressure transducer providing wellbore pressure and preferably a second pressure transducer providing grease pressure at either the manifold or the pump. A programmable logic controller is provided to activate the grease pump upon reaching preset conditions and to deactivate the grease pump upon reaching a second set of conditions such as pressure threshold, time limit, or volume limits of greased pumped.

1 ) A lubrication flow meter system comprising:
 a pump,   a pressure sensor providing an electronic wellbore pressure indication,   wherein the pump provides lubricant at greater than wellbore pressure,   a frack valve having a through bore, a grease cavity, and a port between an exterior of the frack valve the grease cavity;   a programmable logic controller that switches on the pump at predetermined pressure or time intervals,   wherein the programmable logic controller switches off the pump upon reaching predetermined pressure, time, or volume limits.   
     
     
         2 ) The lubrication system of  claim 1  wherein, an alarm is activated upon exceeding predetermined pressure, time, or volume limits.
