General
Two styles of liquid flow indicator calibrated specifically for use with
water and suitable for installation in any plane.
indication only whereas style two can be set to give a switched output
at a required flow rate. It should be noted however that the switch is
not latching and once the flow rate has caused the piston to pass the
switching point the switch will de-activate. If latching is necessary
therefore, a separate (external) circuit containing an a.c. latching relay
is required.
WARNING: This product contains components manufactured from
glass filled polyester and borosilicate glass. Although
robustly
constructed
recommend the following precautions are taken:
1.
DO NOT over-tighten pipe fittings (Max Torque 25 Nm).
2.
Only use pipe fittings and sealing methods recommended for
use with the end couplings provided.
2a.
DO NOT use tapered male pipe fittings.
3.
Although it should not be necessary, PTFE tape may be used,
but must not be allowed to enter pipework/FM unit.
4.
Support pipework and mount the unit in such a way as to
minimise side loading, mechanical shock loads and vibrations
etc.
5.
In use the glass body of this meter is subjected to pressure and
must under NO circumstances be subjected to physical abuse.
6.
DO NOT use if any form of damage occurs, or is suspected to
have occurred during handling or installation.
7.
Protect from frost.
8.
This unit is intended for permanent installation and should not be
used for temporary applications.
9.
The AC switch requires 240 volts to be connected to power the
switching unit. (Therefore, it's not possible to check the switch
operation with a multimeter). The DC version will operate
unpowered.
10.
If the AC switch is to be used to switch a high inductive load,
such as a relay, it is recommended that a mains filter capacitor
(0.1µF 250V AC Class X2) should be fitted in parallel with the
load.
11.
To prevent switch reswitching when indicator passes out of
range, it is recommended to incorporate a latching relay in the
wiring circuit.
