Factory Pre-programmed

The engineers at Eastech Flow Controls realized that for a new product to be successful, it must be simple to install and quickly made operational. In order to accomplish this goal, every Vantage 4000 is shipped to the field factory pre-programmed to the conditions set forth by the customer. Pre-programming specifications are electronically confirmed on the display of the transmitter. If changes to the meter's factory pre-programming is required, re-programming can simply be accomplished on the meter keypad.

Accuracy & Reliability

The Vantage^® 4000 employs the latest DSP microprocessor technology. An exclusive signal processing technique combines correlation and FFT detection methods in order to ensure the highest degree of accuracy and reliability possible.

Rangeability:	40 to 0.1 ft/sec
Turndown:	400:1
Repeatability:	0.25%
Accuracy:	±1% of actual flow

SpeedRail Sensor Mounting

Since the externally mounted sensor is the preferred design for transmitting signals through pipe or conduit, a new one-piece SpeedRailTM sensor mounting system was developed. Mounting of both sensors is quickly and accurately accomplished in two simple steps. Lock the self-aligning mounting rail to the pipe or conduit and load in the sensors.
Once the sensors are connected to the transmitter, the Vantage 4000 is ready to measure flow.

Transmitter
Eastech Flow Controls was the first company to utilize a phase shift detection system in the design of transit-time flowmeters. This technique greatly improves time difference detectability, which in turn, enhances accuracy and operating stability while substantially reducing the effects of noise.
