Catalog excerpts

MACE velocity sensors use continuous wave Doppler ultrasound to measure the speed of dirt, bubbles and other particles in the stream flow. MACE Doppler ultrasonic velocity sensors utilizing MACE Advanced Signal Processing (MASP) technology "see" across the entire stream profile to give a true average velocity. MACE Doppler ultrasonic sensors "see" particles in water like turning on a flashlight in fog. For use in full pipes or partially full pipes when used in conjunction with an EchoFlo ultrasonic depth sensor. Insertion sensors measure velocity only and require access to the outside wall of the pipe in which the sensor is to be mounted. Installation These sensors can be installed into existing pipework through a 2" ball valve (recommended) or just through a 2" female thread fitting. Compatibility The Doppler ultrasonic insert velocity sensor is compatible with the following MACE meters: • MACE AgriFlo XCi (Requires a Doppler card) • MACE FloPro XCi (Requires a Doppler card) • HVFlo Logging Flow Meter TECHNICAL SPECIFICATIONS: Patents: US Patent No. D544,803 AUS Patent No. AU 301464 S Pipe size: 0.1 to 2.54m (4”to 100”) diameter Max. process fitting pressure:1 1034 kPa (150psi) Max. operating pressure:2 253kPa (37psi) 1.8”(D)x 1”(H) Wetted materials: Nickel plated brass and epoxy Pipe intrusion area: 11.25cm2 (1.75 sq.”) 1 The pipe must be de-pressurized prior to insertion or removal 2 The stream flow may be suitable for Doppler ultrasonic flow measurement in pressures >253kPa (37psi) if it contains at least 100 parts per million of suspended solids that are >75 microns in size.

This sensor is used to measure velocity only in full pipes when access to the pipe is available and the pipe can be emptied when installation or maintenance is required. It can also be used in partially full pipes or open channels in situations where the user is measuring depth by a third party or ultrasonic depth sensor. Installation Use a MACE ZX SnapStrap to install this sensor inside a pipe in minutes. The polycarbonate ZX Snapstrap is tough, secure, does not foul and can be easily removed to take the sensor to another site. Compatibility The Doppler ultrasonic area/velocity sensor...
