Note
Dimensioned drawings illustrating the 800 Series Metering Flow Switches are available as
Plumbing Connections
Note
Before connecting a sensor into your fluid line, verify that the normal flow rates expected in that line
are within the operating range of the sensor.
Extended use above the rated maximum flow rate of the sensor will reduce its useable life.
CAUTION
Do NOT use anaerobic pipe sealants such as LOCTITE brand sealants or SWAK with
the 800 Series metering flow switches fitted with a clear polysulfone
faceplate.
The aggressive chemical nature of these materials can cause cracking of the
polysulfone faceplate.
Use Teflon (PTFE) tape or PTFE-based liquid sealants to provide leak-tight and
lubricated junctions at all connection points.
Real-Tuff and Hercules are two of many suitable brands of PTFE-based sealants.
Note
It is recommended that connections to the stainless steel flow sensor be made with stainless steel or
materials of similarly chemical inertness to minimize potential corrosion damage.
Note
The flow response of the sensor, and thus its calibration may be dependent on the internal diameter
(ID) of an incoming pipe, or the ID of a tube connection.
If the ID of your pipe or tube fitting where it connects to the inlet port is LESS than the value shown in
Table 2, calibration values may be invalid.
Appropriate calibration procedures can be applied to allow the 800 Series flow sensor to be used with
pipes and connections with ID’s smaller than those shown in Table 2. Contact Proteus for assistance.
