Section 3 Operation
3-3 Operation of the Model MT3809 Flowmeter with a Transmitter with or without Optional Alarms and
Pulse Output for Totalization
* Start-up the meter as described in Section 3-2.
* Programming performed prior to shipment (parameters).
The transmitter with or without alarms and pulse output is preprogrammed
prior to shipment for the following parameters based on the order
information, meter configuration and application. If parameters are not
specified in the customer purchase order, the defaults inherent to the
electronics will be as shown in (parenthesis).
Transmitter only Transmitter plus
pre-programmed parameters alarms and pulse output
preprogrammed parameters
Model Number Alarm LoLimit (0% FS flow)
Serial Number Alarm HiLimit (100% FS flow)
Tag Name (blank) Pulse output units (1 ppl)
Flow Rate units of measure (lpm) Resettable totalizer units of measure (lit.)
Low Flow cutoff (5% FS flow) Inventory totalizer units of measurement (lit.)
Calibration factor (% scales only)
Analog Output LoRange
(4 mA @ 0% flow)
Analog Output HiRange
(20 mA @ 100% flow)
* Manual programming or reprogramming of the electronics.
Programming of the transmitter with or without alarms and pulse output
may also be done locally via an HART Communicator. Please refer to the
manual of the communicator for detailed description of operation or Figure
3-1.
* Recalibration of analog transmitter output (spanning high and low)
At any time after factory calibration, shipment, installation, or service, the
transmitter can be recalibrated by overwriting any of the previous
calibration point-pairs, assuming that the user can provide a series of
accurate rates of flow through the meter. If preferred, the meter with
transmitter may be returned for recalibration at the Brooks service
department for a fee.
* Basic transmitter setup parameters
These are meter identification parameters set prior to shipment of the
meter.
Flowmeter identification: Model number, serial number, tag name.
Flowmeter configuration: Low flow cutoff, calibration factor, flow rate units of
measure.
Transmitter analog output: Analog output HiRange, analog output LoRange.
* Optional programmable alarm and pulse output parameters and features
Alarm contact output: HiLimit, LoLimit
One or two digital outputs are available for alarm signals. Contact output
polarity is configurable as normally open (N.O.) or normally closed (N.C.).
