Koolance in proud to introduce new INS-FM18 inline flow meter made of stainless steel and brass provides a visual and electronic indicator of real-time coolant flow rate. Just like its predecessor, INS-FM17, the novelty has G 1/4 BSP threads on each end.
To monitor the actual flow rate you should ether connect it to appropriate port on fan controller or to buy additional frequency circuit that multiplies the RPM signal to allow it to be read by most fan tachometer headers (such as those found on ATX motherboards). This signal is intended to allow fan detection software (including BIOS) to enable the appropriate alarm or shutdown procedure if the flow meter impeller stops rotating. The “RPMs” represent approximate flow meter coolant in mL/min, and not revolutions.
Technical details of the novelty are exactly the same as of INS-FM17 flow meter, except for primary materials off course :
- Flow rate range = 1.0-15 LPM (15.6-240 GPH)
- Fluid temperature range = 0 — 70°C (32-158°F)
- Maximum pressure = 6kgf/cm2 (85 psi)
- Product dimensions: 1″ x 1.9″ x 0.75″ (2.5cm x 4.8cm x 1.9cm).
Using stainless steel for body instead of acrylic has resulted in 50% price growth. In fact, MRSP for Koolance INS-FM18 is $29.99 and can it is already available at Koolance e-shop. Perhaps, such price also responds to better flow rate accuracy compared to its predecessor since we know the last is not quite good at it.
Overall this looks more like a revision 2 of INS-FM17 than a completely new product.
