Sierra FastTrak™ 730 Flow Meters

Sierra Instruments’ FastTrak™ 730 Flow Meters provide outstanding measurement accuracy and 200 millisecond response time at a competitive price.

The FastTrak measures the mass flow rate of air and many process gases. The FastTrak meter is available in pipe sizes from 1/4-inch to 3/4-inch and delivers an electronic output signal proportional to total gas mass flow rate.

The FastTrak meter is ideal for monitoring flows of non-corrosive gases compatible with the device’s wetted materials, and applications requiring fast time response. Gas mass velocity is monitored with Sierra’s field-proven fast response thermal mass flow sensor—distinguished by its exceptional accuracy and speed of response.

FastTrak meters are available in several configurations to satisfy every flow monitoring application. Output signal options include 0 to 5 VDC, or 4 to 20 mA, all proportional to gas mass flow rate, in your choice of engineering units.

Features
