Massflow devices - Series PMF01

The flow measurement is used in different areas, Including, for example, leaks in hydraulic valves or the measurement via a fuel injector. In order to measure the flow rate or quantity of a gas or a liquid, flowmeters are used in industrial measurement technology for process optimization. Like all flowmeters, APT's PMF01 flow meter consists of two main components: sensor (transducer) and transmitter. The measuring transducer serves as a flow meter, which determines the physical or chemical properties (eg temperature) and can detect the material nature of its Environment. In the transmitter, the detected values are then converted into electrical signals for further processing and are played out. Possible fields of application for flowmeters are chemicals and petrochemicals, oil and gas, power generation, the pharmaceutical industry and paper production, as well as numerous other sector-specific applications.

Flow tester for precise analysis in Multi-channel test tasks

All over the world, APT PMF01 flow meters are used for the measurement and classification of air flows (leaks in the automatic production process). The flow meter is particularly convincing with a stable design and a high degree of flexibility. The multi-channel capability in combination with up to 32 available test programs also enables the implementation of individual Solutions. The basis for all tests is the mass-flow method. The measurement can be carried out under vacuum or overpressure. In addition, the PMF01 flowmeters are capable of simultaneously measuring larger inflow or outflow mass flows simultaneously at several test Points. Two RS232 interfaces are part of the standard equipment of these flowmeters. Other options include a computer connection via 3964R or ASCII. The integrated LC-display allows a graphical representation of the measurement curves of the individual channels for test purposes. Further advantages are the comfortable parameterization and uncomplicated analysis of the test tasks by means of software. The typical control tasks of the flow meter include the valve seat test on cylinder heads, the injection system test or an oil drilling check, for example on crankshafts.

Areas of application for our flow meter

The flow measurement is used in different areas, Including, for example, leaks in hydraulic valves or the measurement via a fuel injector. The flow meter PMF01 is distinguished by its versatile functions. Thanks to its high flexibility, it easily solves various test procedures and can perform both manual and fully automatic tests. In addition to flow tests with the test medium compressed air, flow tests with vacuum as test medium are also possible. The APT flowmeter is used, among other things, for checking various metal parts - such as valve seats or oil ducts on engine components. In addition, the tightness of plastic parts can be tested.
