"M" Series High Sensitivity Neck Provers:
Seraphin "M" Series High Sensitivity Neck Provers are used in the water draw calibration of displacement type provers and large open tank provers. They are also used for checking the accuracy of slower flow meters (less than 200 GPM) in petroleum and petro-chemical applications. The smaller "M" series measures can be made with a resolution as low as ¼ cubic inch (5 ml) scale increments. All of our provers are available with a Certificate of Traceablility to NIST. Seraphin can also arrange for actual NIST calibration directly after manufacture.
"J" Series Normal Sensitivity Provers:
Seraphin "J" Series Normal Sensitivity open tank measures and provers are our heavy duty provers used to check the accuracy of liquid petroleum meters at bulk liquid terminals.
