A tiltmeter, is a type of instrument used to detect any kind of tilt in the structure to which it is attached. Most tiltmeters use an air bubble in a liquid-filled tube, much like a typical carpenter's level, but are equipped with sensitive electronics that can detect even the tiniest change in tilt. They either sound an alarm or transmit the data to a remote monitor or other device.
The Consistometer is a low cost, durable, instrument for accurately checking laboratory or production samples against consistency, viscosity or flow rate standards.It uses little bench space and is yet probably the simplest, most accurate method of conducting a variety of flow associated tests.he consistometer provides a single parameter for a variety of flow tests which can be carried out over any period under as near identical conditions as possible. The Consistometer or Bostwick Consistometer is manufactured from stainless steel engraved with a series of precise graduations at 0.5 cm intervals.
