仪器简介：
These meters measure flow via pressure drop across a laminar flow element (LFE). Because the flow element makes the flow stream laminar, placement in the process does not require straight pipe runs upstream or downstream of the meter, greatly simplifying installation. The LFEs also provide an outstanding turndown ratio of 100:1 giving the meter a very broad and accurate measuring range. As compared to thermal mass technologies, the LFE design provides an ultrafast response at start-up or input change, often within 20 milliseconds; there is also no thermal drift with this technology.
An integrated keypad around the display is all that is required to program the unit for service梟o additional costs for programming modules. The 0 to 5 VDC output allows transmission of the flow value to a remote display, recorder, or controller regulating a valve or pump.
For portable flow metering applications, order the battery pack listed below. Units can be mounted via threaded taps in the meter body.
Flowmeters include the integrated sensor, display, and transmitter. All models include a 120 VAC power adapter; 220 VAC European adapters.
Meters feature dynamic display that simultaneously shows flow rate, line pressure, fluid temperature. For the unit shown, both power and input/output signals are transmitted through a single multi-pin connector.

Units can be mounted via threaded taps in the meter body. An integrated PID controller directs the unit抯 response to process changes. Set the P and D parameters to tailor the unit抯 response. Flow set-point is established with the optional setpoint control module, a 0 to 5 V signal, or an RS-232 input signal. See the table below to select the optional setpoint module.
