Perfecting Measurement CRYOGENIC PROVER TECHNICAL DATA SHEET CRYOGENIC TRANSFER TRANSPORT SYSTEMS The dream of a quick, simple, and reliable field calibration system for cryogenic flowmetering systems has become a reality with the Cryogenic Transfer Standard. When suitably documented by a NIST traceable laboratory, the system offers users a high accuracy standard of comparison to allow adjustment of bulk transport mounted systems. flowmetering systems for bulk transports has been verified by comparing the metered delivery with the net weight delivered on a certified truck scale. To eliminate road loss errors, the bulk transport had to pump, while on a weigh scale, into a second empty transport off the weigh scale. The low precision resulting from scale necessitated very large sample sizes and lack of control in pumping rates. In addition, the weight measurements could not be made while pumping. This resulted in a time-consuming process where the pump was started and stopped repeatedly and which tied up the two trailers and the weigh scale for typically four hours per calibration check. In addition, when finished, both trailers had to be filled before going to their next delivery. With the Hoffer SY-14B Cryogenic Transfer Standard these problems are eliminated. First, only the trailer to be tested need be present in most cases. The discharge from the trailer is pumped from the through the top fill connection to The system includes a transfer standard turbine flowmeter and a metering run mounted on a hand truck and an electronics console tion of the prover is provided in a small portable electronics enclosure with military style quick disconnect electrical fittings. flowrate and flowing temperature is provided as well as a total flow test total indicator. Temperature LAR, and other product types are provided to allow the total display to be in mass or volumetric units. A prover cable interconnects the transfer standard to the trailer's meter system. A prover switch on and stops both systems electro- nically. The integrally mounted control valve allows the operator to simulate the typical flowrates and delivery pressures to be seen in actual service. You do not have to shut the pump down between test resentative test procedures on how you can reduce calibration costs while exceeding legal metrology requirements, contact our appli- cations group.
