5.8 TEMPERATURE AND PRESSURE RATINGS
We rate our standard (universal) transducers for operation up to 250°F. We offer High (H)
temperature flow transducers rated for operation up to 375°F. We also manufacture Very
High (VH) temperature transducers for applications where the temperature exceeds 375°F,
but is less than 450
°
F.
5.9 OVERVIEW OF SYSTEM 1010BX MEMORY RESOURCES
System 1010BX memory resources include Read-Only-Memory (ROM) and battery-backed Ran-
dom Access Memory (RAM). The ROM memory contains the system operating instructions,
on-line help text, default data, and the pipe, transducer and liquid tables. The Interface De-
tector uses 1 Mega byte of RAM (standard) to provide three discrete storage functions:
Active Memory - Site Storage Memory - Datalogger Memory.
Upon creating a site, the meter copies all ROM-based defaults into the meter’s operation-
al database, the Active Memory . This provides two advantages. First, RAM-based opera-
tion increases performance. Second, this creates an immediate Site Setup, based on the meter’s
defaults. To make the meter operational, you just have to enter the required data (e.g.,
pipe and transducer data) and edit other default settings to suit your application. When
you program the meter, all your entries are retained in the Active Memory. This enables you
to use the meter immediately after finishing a Site Setup. You’re not limited to one
set of site parameters. You can copy site data from Active Memory to Site Storage Memory .
Site Storage Memory provides permanent storage area for several inactive Site Setups.
The multi-site storage feature allows rapid reinstallation at many locations. All you have
to do to reactivate an inactive Site Setup is to recall it back into to Active Memory . However,
be aware that this action over-writes ALL data residing in the Active Memory area.
The Datalogger logs data collected at preset intervals during operation. It uses the system
RAM resources independently of Active Memory and Site Storage Memory . Therefore, data
movement between Active Memory and Site Storage memory will not affect it directly. How-
ever, all stored data shares a common RAM pool. The meter allocates the actual amount of
bytes available for each storage function dependent on the demands of each facility. There-
fore, an unusually large Datalogger file may reduce the amount of site storage memory avail-
able. Storing several inactive site setups may reduce the available logging capacity.
If you receive a [Memory Full!] message when you try to save a Site Setup, you will have to
delete an obsolete Site Setup or clear the Datalogger Memory to make room. Another Data-
logger memory consideration applies to dual-channel systems, when both measurement chan-
nels are actively logging data. Dual-channel meters store logged data from BOTH channels in
a common file so you must include Site ID for each line to identify the applicable measure-
ment channel.
The 1010BX also offers a Memory Map and Defragmenting command in the Meter Facilities
area of the menu as an aid in visualizing and maximizing the efficient utilization of your meter’s
memory resources.
