Product Description
Product description:
TTSD-model vehicle-mounted gas flow standard device (hereinafter referred to as the vehicle-mounted device) selects to use the Roots flowmeter or turbine flowmeter with high accuracy as the master meters. It could be used for delivery and periodic calibrations of displacement or velocity-type flowmeters by using basic principles of master meter method devices as well as related regulations of gas flowmeters. This device not only has features of normal devices of master meter method , but also has unique design structure and applications. This standard device is placed on a vehicle , which makes it possible to reach the user target place easily. The calibration can be done with only power supply and small space ,thus the calibration time and fee is saved significantly
