TracerVM™
Operating Instructions
Applies to VM lowmeter models.
General
The TracerVM Electronic lowmeter is a non-display flow and
temperature sensor that provides a 0.5 - 3.5 Volt output only. It is
flow-direction specific. Refer to the arrow on the body for correct
flow direction. low in the opposite direction of the arrow will yield
inaccurate voltage output. low sensor technology is vortex shedding
behind a bluff body.

D rect ves
low sensors are in conformity with these Council
directives on the approximation of the laws of the
EC member states:
• Low Voltage Directive (2006/95/EC)
- Standards used: EN 61010-1:2001
• EMC Directive (2004/108/EC)
- Standards used: EN 61326-1:2006 and 61326-
2-3:2006
Smartflow Vortex flow sensors fall under Article 3,
§3 of PED Directive 97/23/EEC and are therefore
not required to be CE-marked according to this
directive.

Limited Warranty
Seller warrants that this product supplied will conform to the description herein stated and that the product will be of standard quality.
This is the sole warranty made by Seller with respect to this product. Seller expressly disclaims any other express or implied warranties,
including, but not limited to, the implied warranty of merchantability and the implied warranty of fitness for a particular purpose.
Seller shall not be liable for any cost or damages, whether direct, incidental or consequential, including, but not limited to, any injury,
loss or damage resulting from the use of this product, regardless of whether any claim for such cost or damages is based on warranty,
contract, negligence, tort or strict liability. The sole liability of Seller is limited to repairing or replacing this product.
this warranty shall not apply to any products that have been repaired or altered by anyone other than Seller. The warranty shall not apply
to any products subject to misuse due to common negligence or accident, nor to any products manufactured by Seller which are not
installed or operated in accordance with the printed instructions of Seller or which have been operated beyond the rated capacity of the
goods. Seller states that the product’s useful safe life is 5 years. Actual life may vary widely depending on operating environment such as
temperature, pressure, and chemical exposure. Users are cautioned to refer to instructions for operating limits and a partial list of
incompatible chemicals.
Maintenance Instructions
Copper Plumbing Alert
DO NOT connect an aluminum body flowmeter
directly to copper plumbing. Galvanic corrosion is
very likely to occur. Stainless steel body material is
strongly recommended for this application. Contact
the factory for more information.
Installation Instructions
P pe Conf gurat on
Best flow rate accuracy is achieved when plumbing a straight run of
pipe equal to 10 pipe diameters on the inlet side of the Tracer
flowmeter and a straight run of pipe equal to 5 pipe diameters on the
outlet side of the flowmeter.
Use appropriate pipe sealant to prevent leakage on inlet and outlet
sides of the flowmeter.
Flow and Mount ng D rect on
The Tracer flowmeter must be installed with the flow arrow pointing
the same direction as the process flow. low in the opposite direction
of the arrow will yield inaccurate voltage output. The meter may be
installed in any orientation, horizontally, vertically, or at an angle.
The presence of air bubbles will create an inaccurate analog output.
Power
Attach the power and switching connections to the bare wires of the
cable according to the chart at right. Individual wires are 24AWG
stranded copper. Attach 5VDC power to the unit for correct
operation.
EMI/RFI Interference
Care should be taken to route power and signal cable away from
motors and pumps. Signal integrity may be adversely affected by
close proximity of the wiring to machinery producing high frequency
emissions.
Cable
Maximum effective cable length is 2.9M (19.5ft) as supplied.
Splicing extra length to the cable is not recommended.
