The Meriam Process Technologies (Meriam) Model M1500
Digital Pressure Transmitter is a compact, NIST traceable,
precision measurement instrument available in a wide variety of
pressure ranges and communication / output options. Models
are available for differential, gauge, compound and absolute
pressure measurements. Output options include analog (4­20mA, 0-5V and two SPST switches) or digital (RS-232, RS­485 or USB) models. Communication with digital M1500’s is
achieved using Meriam Serial Protocol (MSP), the Meriam DLL
or LabVIEW®. Digital units have an option of dual pressure
sensors in one unit (any non-differential pressure combination).
Personal computer (PC) configuration software is included. The
software can be used to configure digital transmitters for use
and is required to set up analog transmitter models.

To configure an M1500 with analog output, connect the unit to a host PC using a USB type A to USB type mini-B
cable as shown in the diagram below. The USB connection will power the M1500 and provide communication for
configuration setup when connected to high power (500 mA) USB ports or powered USB hubs. Open the M1500
Meriam Setup Utility application to configure the transmitter as desired. See the “Installation and Operation” section of
this manual for additional information.

Mounting Options

Mounting Options

Mounting OptionsMounting Options

M1500 mounting options include panel and DIN rail mount. Both are standard on all models and hardware is included

with shipment.

Panel mounting is achieved using the cut out and mounting hole guides below. Plan the mounting hole locations so

the P1 (HI) and P2 (LO) ports will be in the desired position upon completion. The four Port Manifold template is only

used for M1500-DIxxxx models with optional flushing ports.

4

Panel Mounting Template for 4 Port Manifold

(M1500-DIxxxx with optional flushing ports)

Once the panel cut out is made and the mounting holes are drilled, remove the corresponding set of diagonal screws
from the M1500 pressure manifold. Insert the M1500’s pressure manifold through the rear of the panel cut out. Locate
the longer panel mounting screws supplied with the M1500, install them through the panel holes, and thread them into
the vacated holes in M1500 pressure manifold. Tighten as needed. A completed panel mount is shown below.

The factory installed DIN rail clip may be removed from the M1500 enclosure if desired for panel
installation. Use a Phillips head screw driver to remove the mounting screw and clip. Reinstall the

screw to prevent debris from entering the enclosure.

DIN rail mounting is accomplished using
the factory-installed DIN clip located on
the edge of the M1500 enclosure. DIN
rail mounting is excellent for mounting
several M1500s in close proximity to one
another, either inside a protective
enclosure, or on a convenient mounting
surface or wall. For high vibration
applications use the longer panel mount
screw to secure enclosure to DIN rail.
