This is a flowmeter that works by the venturi effect. The formula to calculate the flow speed is: c1 = sqrt( 2 (p1 - p2) / rho (A1^2/A2^2 - 1)) In this case r1 = 2mm and r2 = 0.9mm. The fluid is also usually pressurized air where we know…
STL are to build a case for ESP8266 combined with OLED display 128X34. I use with pulse flowmeter for water consumption. Here the link : *ESP8266 V3 :…
This is a stand to hold a Dwyer Rate-Master Polycarbonate Flowmeter (Model A) upright on a desk surface. Dwyer expects you to mount these to vertical surfaces, but if you are doing some basic testing with temporary set ups, you don't want…
Se coloca el soporte con el caudalímetro en la parte más alta de la máquina, para asegurarse que la burbuja de aire no quede en el tubo del laser. Habrá que hacer dos agujeros pasantes en la chapa y montar el soporte con dos tornillos…
The Vaf flowmeters with the large digit readout heads only allow certain mounting positions due to the count reset handle. I needed to mount the head in the ‘problem’ position, so came up with this adapter to extend the handle. The…
Hello community, I've designed a small improvement for the METROVENT DN75 ventilation flowmeter. The Problem: The METROVENT flowmeter is a fantastic device for accurately measuring and balancing residential ventilation systems. However,…
Has the seal of your flowmeter's poppet assembly failed? Disappointed that the only solution seems to be a new assembly part or a rebuild kit for half or more of the cost of the unit itself? Dig out that failed elastomeric compound and…
